A: Cosmetic repair is a specific and measurable thing: ingredients deposit on and into damaged areas, smoothing the cuticle and restoring measured properties such as strength and combability. In an in-vitro study on human hair swatches, this shampoo repaired hair damage up to 94% in one wash. Because the effect is deposited rather than structural, it is renewed with each wash - which is why regular use is what keeps hair feeling its best.

A: Two to three times a week is typical for damaged hair. Because the repair effect is deposited rather than permanent, consistency matters more than any single wash.

A: Proteins work best in balance with moisture. This formula contains hydrolysed keratin, wheat protein and collagen, which is what makes it effective on damaged hair. If you have fine or low-porosity hair, alternating it with a moisture-focused shampoo keeps that balance right.

A: It works well on fine hair used as a treatment wash rather than every wash, since the protein and conditioning polymer load is generous. Keep conditioner to the mid-lengths and ends to keep the roots light.

A: This study measured damage repair on hair fibres, which is a fibre endpoint rather than a growth one. Stronger, less-broken hair often reads as longer hair, because more of the length you grow stays on your head. Growth rate itself is set at the follicle.

A: That is what it is built for. Frizz and heat damage both come from a lifted, roughened cuticle, and the proteins and cationic polymers here work by smoothing exactly that. It is sulfate-free and silicone-free, so smoothness comes from deposition rather than a silicone coating.

A: The formula is sulfate-free, silicone-free and paraben-free, which is the profile generally preferred for chemically processed hair. Colour retention was not measured in this study.

A: The study measured a single wash. Cosmetic fibre repair is deposited rather than structural, so it is renewed each time you wash - which is why a regular routine keeps hair feeling its best.

A: The study tested the finished formula, where the ingredients work together. Hydrolysed keratin and the conditioning polymer system carry the established published evidence for improving damaged fibre properties, with fermented rice water as the formula’s signature ingredient and its long tradition of use.

A: It helps. Damaged hair is at its most fragile when wet, and conditioner reduces the friction during combing that causes further breakage. Apply to mid-lengths and ends.

A: It signals the maximum result recorded in the test. Keeping the phrase means the figure is reported exactly as the laboratory certified it.

A: It was tested on human hair swatches in a laboratory, which is what in-vitro means - a controlled, reproducible way to measure fibre performance.

With a combination of treatment and habit. Products deposit into damaged cuticle areas, smoothing them and restoring measured strength and combability - this shampoo repaired hair damage up to 94% in one wash in an in-vitro study on hair swatches. Alongside that, less heat, gentler wet-combing and regular trims are what keep new damage from accumulating.

It has a long, genuine history of traditional use across East and South Asia, and it is the signature ingredient in this formula. Working alongside it, hydrolysed keratin and the conditioning polymers are the components with an established published evidence base for improving damaged hair - together they are what produced the measured result.

If you are making it at home, rinse or soak rice, keep the water, apply after shampooing, leave a few minutes and rinse. Two things worth knowing: fermented rice water is best diluted and patch tested, and protein-heavy routines suit fine hair better when alternated with a moisture wash. A formulated product adds consistency from wash to wash and a preservative system that keeps it stable.

There is no good evidence that it does. Rice water is a fibre treatment rather than a scalp one - it makes hair stronger and smoother so more of the length you grow stays on your head, which is often what people notice. This shampoo’s study measured damage repair on hair fibres.

Start by identifying which kind you have. Damaged hair snapping mid-length is breakage, and that is what this shampoo addresses directly. Hair released from the root is shedding, driven by hormones, nutrition and thyroid function, and is best addressed alongside your topical routine.

One that is sulfate-free, protein-containing and conditioning - which is exactly this formula’s construction. Proteins work best in balance with moisture, so on fine or low-porosity hair, alternating a protein shampoo with a moisture-focused one keeps that balance right.

Around 50 to 100 hairs a day is completely normal. With damaged hair it can look like more, because broken mid-shaft pieces collect alongside naturally shed hairs - which is exactly what a conditioning, protein-containing shampoo helps to reduce.

Hydrolysed keratin deposits on and into damaged hair and improves measured fibre properties, which is real and published. It works differently from a salon keratin treatment, which chemically restructures the hair - a keratin shampoo delivers surface repair that is renewed with every wash, which is why it suits regular use.
