I've been using the complete keratin treatment for just over 2 weeks, and I noticed a real difference after the very first few washes. My hair feels softer, smoother and much easier to style, WITHOUT FRIZZ!!! The whole routine feels incredibly luxurious. It genuinely feels like a premium salon treatment at home

Clean, weightless volume for fuller-looking hair.

PART OF THE KERATIN TREATMENT COLLECTION
Begin with volume. Complete the ritual with coordinated care.
This shampoo is the cleansing first step in the DIHCAR Keratin Treatment Collection. Use it alone for fresh, fuller-looking hair, or combine it with the Keratin Treatment Conditioner, Keratin Intense Treatment Mask and Keratin Hair Treatment Mist for a more complete routine supporting softness, smoothness, body and protection against the visible effects of breakage.
WHY MANY VOLUME SHAMPOOS DISAPPOINT
Volume should not come at the expense of softness.
Many volumising shampoos rely on harsh cleansing or a temporary rough texture that can leave the hair dry, tangled and difficult to manage. Others coat the roots and make fine hair feel heavy again. DIHCAR takes a more considered approach: effective cleansing, scalp refreshment, moisture support and lightweight conditioning in one salon-inspired formula.
Volume with a dry, rough finish
Over-cleansing may create temporary body while leaving the lengths uncomfortable or difficult to comb.
Big promises without a clear formula story
“Thickening” claims feel less convincing when the cleansing system and supporting ingredients are not explained.
THE FORMULA STORY
Keratin, caffeine, rosemary and mineral moisture support in one refined cleanse.
The formula combines hydrolyzed keratin with caffeine, rosemary oil, Sodium PCA and Zinc PCA. A balanced cleansing system removes excess oil and residue while conditioning ingredients help preserve softness, smoothness and a more polished finish.
Hydrolyzed keratin
Selected to support smoother-looking strands and help reduce the visibly rough feel associated with breakage.
Caffeine
Included to complement a fresh, invigorating scalp-care experience.
Organic rosemary oil
Aromatic botanical care that contributes to the shampoo’s fresh, clarifying character.
Sodium PCA
A naturally occurring moisture-supporting ingredient that helps hair feel softer after cleansing.
Zinc PCA
Included to support a clean, balanced scalp feel without a heavy conditioning finish.
Lauryl glucoside + coconut-derived cleansers
A carefully balanced surfactant system designed to cleanse effectively while maintaining a refined hair feel.
WHAT IT IS DESIGNED TO SUPPORT
One shampoo. Three essential benefits.
Visible root lift and body
Helps remove excess oil and residue that can weigh hair down, leaving it fresher and fuller-looking.
Soft, smooth lengths
Keratin and conditioning ingredients support a polished feel instead of the dry texture left by many volume shampoos.
A refreshed scalp
Caffeine, rosemary oil, menthol and Zinc PCA contribute to a clean, invigorating washing experience.
HOW TO USE
The first step in a fuller-looking hair ritual.
-
01
Wet thoroughly
Saturate the scalp and lengths with warm water.
-
02
Massage into the scalp
Apply a small amount and massage gently through the roots until a soft lather forms.
-
03
Rinse completely
Rinse well. Repeat only when needed after heavy styling-product use or excess oil.
-
04
Follow with targeted care
Use the Keratin Volume Boost Conditioner on the mid-lengths and ends. Add the mask weekly and mist as a leave-in finishing step.

Everything to know before your first wash.
Who is this shampoo best suited to?
It is especially relevant for fine, flat or low-volume hair, oily roots, product build-up and hair that needs freshness without a heavy finish. It is suitable for all hair types when individually tolerated.
Will it make my hair feel dry?
The formula is designed to cleanse thoroughly while supporting softness with Sodium PCA, PCA Glyceryl Oleate, Glyceryl Oleate and hydrolyzed keratin. Follow with conditioner on the lengths if your hair is dry, porous, coloured or chemically treated.
Can I use it on coloured hair?
It may be used on coloured hair, but individual colour retention depends on the dye, hair porosity and washing frequency. If your colour is especially delicate, patch-test on a hidden section or consult your colourist.
How often should I use it?
Use according to your scalp and hair needs. Many users may use it two to four times per week, while oilier scalps may prefer more frequent cleansing. Avoid over-washing if the lengths feel dry.
Does it help with hair growth?
This is a cosmetic shampoo designed to cleanse, refresh the scalp and support fuller-looking hair. It is not a medicine and is not intended to treat hair loss or medically stimulate new hair growth.
Can sensitive scalps use it?
It may be suitable when individually tolerated, but the formula contains fragrance, rosemary oil, peppermint oil, menthol and aromatic components. Patch test first and discontinue use if irritation occurs.
Can it be used during pregnancy or breastfeeding?
It is a rinse-off cosmetic product, but natural certification does not guarantee suitability for every individual. For additional reassurance, show the complete ingredient list to your doctor or midwife.
Are results guaranteed?
DIHCAR stands behind the quality, authenticity and intended cosmetic performance of the formula. From the first wash, hair is designed to feel clean, refreshed and lighter at the roots. The formula combines hydrolyzed keratin, caffeine, rosemary oil, Sodium PCA and Zinc PCA rather than relying on one vague “volume” claim. The final visible result still varies according to hair density, condition, styling method and consistency of use.
What makes it different from an ordinary volume shampoo?
It combines certified natural-cosmetics standards with a clear ingredient story: hydrolyzed keratin for a smoother-looking hair feel, caffeine and rosemary for an invigorating scalp-care experience, Sodium PCA for moisture support and Zinc PCA for a fresh, balanced finish. It is COSMOS NATURAL certified and contains 99% ingredients of natural origin.
Does it contain fragrance?
Yes. It has a fresh aromatic profile with peppermint, rosemary, vanilla-like sweetness, tonka and sandalwood nuances. Review the complete INCI before use if you are sensitive to fragrance or essential-oil components.
