The Science Behind Every Bar

Every Bar and Bar formula is built around clinically proven, salon-grade actives — not marketing buzzwords. Here's exactly what's in each product, why we chose it, and what the science says.

Grow + Protect

Hair growth support & heat protection — Fragrance: Gingerlily Rain

CAPIXYL™ — Shampoo active (Peptides & Red Clover)

CAPIXYL™ is a patented active complex that combines a biomimetic peptide with a red clover flower extract rich in biochanin A. Biochanin A is a powerful flavonoid that inhibits 5-α-reductase — the enzyme linked to hair thinning and loss. The peptide works alongside it to stimulate tissue remodeling, improving hair anchoring at the follicle level and supporting stronger, more resilient growth over time. The combination works synergistically: the peptide rebuilds, the biochanin A protects.

EssentiaTein® Protect — Shampoo active (Rice, Baobab & Amaranth)

EssentiaTein® Protect uses a targeted enzymatic process to deliver multi-benefit protection in a single ingredient. Derived from a sustainable trio of rice, baobab, and amaranth, it repairs the hair cuticle from damage caused by UV rays, locks in essential hydration, and enhances shine. Think of it as an environmental defense system for your hair — neutralizing the daily oxidative stress caused by sun exposure, pollution, and heat styling.

ThermoShield Premium — Conditioner active (Chia Extract)

ThermoShield Premium is a heat protection active derived from chia seed extract. It works by retaining water within the hair fiber and forming a protective film around each strand before heat is applied. Critically, it achieves this without compromising your ability to style — your hair still responds to heat tools, but the fiber is shielded from the temperatures that cause structural damage and breakage.

ProShine — Conditioner active (Castor Oil Esters)

ProShine is a 100% plant-based ester system formulated under Green Chemistry principles. It activates intense shine by interacting with the proteins in the hair fiber and increasing the fiber's refractive index — essentially making each strand more reflective of light. It also enhances color vibrancy, making it particularly effective on color-treated hair.

Thick + Voluminous

Volume & density for fine hair — Fragrance: White Blossom + Fig

DensiFoll™ — Shampoo active (Mallow & Hydrolyzed Rice Protein)

DensiFoll™ is a 99% naturally derived bio-active powered by plant stem cell exosomes enriched with small RNA and hydrolyzed rice protein. It stimulates the key genes responsible for hair growth and promotes denser, thicker hair — making it one of the most targeted ingredients available for thinning hair. Beyond density, DensiFoll™ also reinforces the scalp's barrier function, supporting a healthier follicle environment from which stronger hair can grow.

NaturePep® Amaranth — Shampoo active (Amaranth Peptides)

NaturePep® Amaranth works from the inside out. Rather than coating hair with a surface film, it penetrates the hair fiber itself to physically increase the diameter of individual strands — resulting in hair that is measurably thicker and fuller. It also reduces friction between strands, allowing for more natural movement while reducing the mechanical damage that comes from daily brushing and styling.

Tilicine® — Conditioner active (Linden Tree Bud Extract)

Tilicine® is an extract from the buds of the linden tree (Tilia tomentosa), rich in phytohormones, polysaccharides, and proteins. For fine hair, it delivers long-term moisture retention within the hair fiber, smooths and coats the hair surface to reduce static, and measurably improves volume and body. Unlike heavy conditioning agents that weigh fine hair down, Tilicine® conditions without sacrificing lift.

CAPIXYL™ — Conditioner active (Peptides & Red Clover)

The same clinically proven growth-support complex used in Grow + Protect also anchors the Thick + Voluminous conditioner. For fine or thinning hair, supporting the follicle while improving strand diameter is a dual approach to visible density — thicker individual strands plus more strands over time.

Clarify + Balance

Oily hair & scalp rebalancing — Fragrance: Vanilla & Sage

Bicobiome® Scalp — Shampoo active (Niacinamide, Lactobacillus & Salicylic Acid)

Bicobiome® Scalp is a multi-active system that works in four targeted steps to rebalance the scalp microbiome. Using Bicosome® delivery technology, it sends niacinamide deep into hair follicles to regulate oil production and reduce inflammation. Simultaneously, a postbiotic Lactobacillus ferment normalizes the fungal microbiome at the skin's surface layer, salicylic acid gently dissolves dead skin cells and dandruff flakes, and the bicosome lipid structures themselves repair the skin matrix. Clinically proven to restore microbiome balance, reduce sebum, and clear dandruff within 28 days.

TRIcare™ CG — Shampoo active (Amino Acids)

TRIcare™ CG is clinically proven to reduce sebum, minimize pore size, and calm redness by inhibiting 5-alpha reductase — the enzyme that triggers excess oil production. It is microbiome-friendly certified and designed to address the root cause of oiliness rather than simply stripping the scalp's surface. The result is a scalp that stays balanced longer between washes, without the tight, dry feeling that harsh clarifying formulas often leave behind.

SEBORILYS — Conditioner active (Willowherb, Terminalia, Nasturtium & Microalgae)

SEBORILYS is a botanical blend that tackles sebum from four different angles: willowherb tannins slow sebum production via anti-androgenic activity; terminalia provides astringent tightening; nasturtium delivers antimicrobial defense against scalp bacteria; and zinc derived from microalgae calms inflammation. Together they extend the clean, fresh feeling of a wash without over-drying hair or scalp.

5α-Avocuta® T — Conditioner active (Upcycled Avocado Esters)

5α-Avocuta® T is a natural oil-based active made from upcycled avocado butyl esters. It regulates sebum secretion by inhibiting 5-α-reductase activity — the same enzymatic pathway that drives excess oil production. Being oil-based, it also delivers lightweight conditioning to the hair shaft, so oily-scalp hair gets moisture at the lengths without adding heaviness or shine at the roots.

Health + Hydration

Deep moisture for dry hair & scalp — Fragrance: Sea Moss

Fision® EcoSil — Shampoo active (Olive Squalane)

Fision® EcoSil is a versatile emollient derived from upcycled olive squalane — a natural alternative to traditional silicones. It delivers the slip, shine, and smoothness of silicone without the buildup that silicone causes over time. It is particularly effective on UV-damaged hair, where it restores wet combability and reflective shine in a single application. Being biodegradable and sustainably sourced, it aligns with Bar and Bar's plastic-free, low-impact formulation ethos.

Baobab Tein NPNF® — Shampoo active (Baobab Oligopeptides)

Baobab Tein NPNF® is a 5-in-1 bioactive ingredient built from oligopeptide technology derived from baobab — one of Africa's most resilient plants. In a single ingredient, it repairs structural damage to hair fibers, increases hair strength, protects against UV-induced degradation, deeply moisturizes dry hair, and nourishes strands from root to tip. The "anti-aging for hair" positioning is accurate: it addresses the cumulative damage that makes hair look dull, brittle, and lifeless over time.

TerraCera™ Renew NP — Conditioner active (Plant-Derived Ceramide)

TerraCera™ Renew NP delivers a breakthrough plant-derived ceramide through precision bio-fermentation, ensuring exceptional purity and efficacy. Ceramides are lipids naturally found in the hair cuticle that bind its overlapping scales together — when ceramide levels are depleted through heat, chemical processing, or environmental damage, hair becomes porous, frizzy, and prone to breakage. TerraCera™ replenishes these ceramide levels, measurably reducing Trans-Epidermal Water Loss (TEWL) and restoring the hair's natural moisture-sealing barrier.

Fision® Hydrate Pro — Conditioner active (Hyaluronic Acid & Amino Acids)

Fision® Hydrate Pro is formulated to mimic the scalp's own Natural Moisturizing Factors (NMF) — the compounds the skin produces to retain water at a cellular level. It combines hyaluronic acid, wholesome amino acids, and Pro-Vitamin B5 in a single delivery system. Clinically demonstrated to deliver statistically significant moisturization at both 24 and 48 hours post-application, making it one of the more rigorously tested hydration actives in the line.

Bond + Repair

Bond rebuilding for damaged & over-processed hair — Fragrance: Luxe Cashmere

EverBond™ — Shampoo & Conditioner active (Moringa)

EverBond™ is a natural bonding technology derived from Moringa oleifera seed extract. It penetrates the hair cortex — the innermost structural layer — and bonds directly with keratin sites to restore the hair's internal architecture. Specifically, it repairs disulfide bonds: the chemical bridges that give hair its strength and hold its natural shape. These bonds are broken by bleaching, chemical relaxers, excessive heat, and mechanical stress. EverBond™ rebuilds them. Benefits are visible after a single application with no buildup after repeated use.

Restart PRO — Shampoo active (Chia, Flaxseed, Itaconic Acid & Panthenol)

Restart PRO is a cross-linking active built on the synergistic combination of itaconic acid, arginine, Pro-Vitamin B5 (panthenol), and polysaccharides extracted from chia and flaxseed. Together these compounds provide a repair and protection mechanism specifically targeting chemically damaged hair — the kind of structural damage caused by bleaching, dyeing, perming, or relaxing. It works alongside EverBond™ to address both the bonds themselves and the structural proteins surrounding them.

EcoPep — Conditioner active (Oat Peptides)

EcoPep is a natural, sustainable oat peptide scientifically proven to revitalize hair from the scalp outward. Its clinically documented benefits include reduced hair fall, enhanced hair density and thickness, repaired and strengthened hair fibers, and protection against premature hair aging. For hair that has been significantly processed or damaged, EcoPep works at the follicle level to improve the quality of new growth — not just the appearance of existing hair.

Curl Define + Moisture

Deep moisture & curl definition for curly, coily & textured hair — Fragrance: Santal and Amber

Fision® HydraTress — Shampoo active (Hyaluronic Acid, Pea Peptide & Quinoa Protein)

Fision® HydraTress was developed specifically for frizz control and moisture balance across all hair types and environments. It combines quinoa protein, pea peptide, and hyaluronic acid — all plant-based and vegan compliant. A single application delivers 24-hour frizz protection in any humidity level, while improving shine, softness at the ends, and manageability. For curly and coily hair, where moisture retention is a persistent challenge due to the tight coil structure, HydraTress provides a meaningful, lasting hydration boost that doesn't require heavy oils.

TRIspire Vitalize — Shampoo active (Pro-Vitamin B5)

TRIspire Vitalize combines Pro-Vitamin B5 (panthenol) with a long-chain quaternary compound that increases how strongly the active adheres to the hair fiber. This enhanced substantivity means the conditioning and frizz-control benefits persist even after rinsing and subsequent washes — no buildup accumulates, but the benefit remains. Proven to control frizz in high humidity after 24 hours and to improve manageability from the first application.

Batana Oil — Conditioner active (Elaeis oleifera)

Batana oil is extracted from the American palm (Elaeis oleifera), traditionally used by the Miskito people of Honduras for hair health. Unlike lighter oils that sit on the hair's surface, batana oil penetrates the hair shaft, delivering deep, lasting hydration directly where curly and coily hair needs it most. Regular use improves elasticity and reduces breakage — critical for kinky and coily textures that are prone to snapping under manipulation. It also carries natural anti-inflammatory and antimicrobial properties that soothe dry, itchy scalps and support a healthier growth environment.

Phytovie® Defense — Conditioner active (Brassica Oil)

Phytovie® Defense is a natural film former derived from Brassica oil that functions as both an emollient and a protective barrier. For curly hair, it provides three things simultaneously: intense moisture retention, a protective film that shields the cuticle from humidity-induced frizz, and thermal protection for heat styling. It coats the hair surface without silicone heaviness, making it compatible with curly hair's need for moisture-rich but non-weighty conditioning.

Smooth + Sleek

Anti-frizz & smoothing for frizzy, humidity-prone hair — Fragrance: Santal

Fision® HydraTress — Shampoo active (Hyaluronic Acid, Pea Peptide & Quinoa Protein)

The same 24-hour frizz-control active used in Curl Define + Moisture anchors the Smooth + Sleek shampoo. For straight and wavy hair that battles humidity and flyaways, HydraTress delivers moisture balance that smooths the cuticle from the inside rather than coating it from the outside. The result is sleeker, shinier hair that holds its shape even in high-humidity conditions.

TRIspire Vitalize — Shampoo active (Pro-Vitamin B5)

TRIspire Vitalize enhances the longevity of frizz control by anchoring its Pro-Vitamin B5 complex firmly to the hair fiber. Its proven 24-hour humidity resistance makes it an essential partner to HydraTress in the Smooth + Sleek formula — one ingredient controls frizz in the wash, the other ensures that control lasts through the day.

Phytovie® Defense — Conditioner active (Brassica Oil)

In Smooth + Sleek, Phytovie® Defense provides the smoothing and sealing function. Its natural film-forming properties flatten the hair cuticle and create a humidity-resistant barrier that prevents moisture from the environment from entering the fiber — which is the direct cause of frizz and puffiness in straight and wavy hair types.

Allinea — Conditioner active (Alpha-Hydroxy Acids, Chia, Lignin & Smectite Clay)

Allinea is a unique fiber-realignment active developed to reduce hair volume and frizz through a synergistic combination of alpha-hydroxy acids, ethyl esters, a disaccharide, smectite clay, coconut triglycerides, and lignin — a biopolymer from renewable plant sources. Where Phytovie® Defense seals the cuticle, Allinea physically realigns hair fibers to lie flatter and more uniformly, reducing bulk and frizz at a structural level for noticeably smoother, sleeker results.
