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

BEFORE ANOTHER SALON APPOINTMENT
For the moment when your roots fall flat—but you do not want another costly volume service.
Blow-dries, root-lifting appointments, scalp treatments and repeated styling services can create temporary volume, but they also require time, maintenance and ongoing spending. DIHCAR gives you a serious cleansing and volume-supporting first step at home.
No styling-dependent promise
Supports fresher, lighter roots before blow-drying, rather than relying only on a professional finish.
No heavy residue cycle
Designed to remove excess oil and build-up that can quickly collapse fine or low-volume hair.
DIHCAR is a cosmetic shampoo. It does not reproduce the instant styling effect of a professional blow-dry or permanently increase the number or diameter of hair fibres.
PART OF THE KERATIN TREATMENT COLLECTION
Begin with lighter roots. 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 conditioner, intensive mask and leave-in for a complete wash-to-finish routine.
WHEN THE OPTIONS FEEL INCOMPLETE
Another harsh volume shampoo—or another expensive salon styling cycle?
Conventional volume shampoos may create temporary roughness through aggressive cleansing, while salon blow-dries and root-lifting services deliver a professional finish that must be repeatedly maintained. DIHCAR offers certified natural-origin cleansing care for fuller-looking hair at home.
Heavy residue and flat roots
Oil, styling build-up and rich residue can make freshly washed hair lose lift quickly.
Harsh cleansing for temporary body
Some formulas create lift by leaving the lengths rough, dry or difficult to detangle.
Repeated salon-dependent volume
Blow-dries and root-lifting services can look impressive, but the effect depends on repeated appointments and styling.
THE KERATIN VOLUME DIFFERENCE
More than cleansing: keratin, scalp refreshment and lightweight moisture support.
A conventional volume shampoo may rely mainly on strong cleansing or a roughened feel. DIHCAR combines hydrolyzed keratin, caffeine, organic rosemary oil, Sodium PCA and Zinc PCA with a balanced cleansing system to support fresh roots, soft lengths and a more polished, fuller-looking 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.
CERTIFIED NATURAL FORMULATION
Natural-origin scalp and volume care with transparent standards.
This is not an undefined “clean hair” promise. The shampoo is COSMOS NATURAL certified, contains 99% ingredients of natural origin and includes 4% ingredients of organic origin.
COSMOS NATURAL
Certified to the COSMOS standard for natural cosmetics. This is distinct from COSMOS ORGANIC.
99% natural origin
The formula contains 99% ingredients of natural origin.
4% organic origin
Selected ingredients, including rosemary and peppermint oils, come from organic farming.
Gluten Free + Nut Free
Formulated without gluten-derived or nut-derived ingredients.
WHAT IT IS DESIGNED TO SUPPORT
One cleansing treatment. 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.
VOLUME WITHOUT AN AGGRESSIVE SALON PROCESS
A fresh, fuller-looking foundation without turning wash day into a chemical treatment.
DIHCAR is a rinse-off cleansing formula. It does not chemically straighten, perm or permanently thicken the hair, and it does not require heat activation or a professional processing service.
No chemical reshaping claim
Designed to cleanse, refresh and support fuller-looking hair—not to permanently alter the fibre structure.
No heat activation
Use it as a normal shampoo. No flat-iron sealing, processing time or specialist equipment is required.
No professional styling dependency
Creates a cleaner, lighter foundation for volume before styling, without requiring a salon blow-dry.
Some professional smoothing or reshaping services use strong chemical systems and high heat. DIHCAR is a COSMOS NATURAL rinse-off shampoo, not a straightening, perming or chemical smoothing treatment.
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.

How volume is created
Professional blow-drying, tools, root lift or service-specific techniques
Removes excess oil and residue to create a lighter foundation before styling
Duration
Styling result is temporary and appointment-dependent
Supports clean, refreshed roots with every wash
A professional blow-dry or root-lifting service can create styling effects that shampoo alone cannot reproduce. DIHCAR is positioned as the serious at-home foundation before styling—not as an identical replacement for professional technique.
WHAT TO EXPECT
Immediate freshness. More polished volume with consistent care.
Clean, refreshed roots
Hair may feel lighter, cleaner and easier to lift after rinsing and drying.
Softer, smoother-looking lengths
Conditioning ingredients and keratin support a more polished and manageable hair feel.
Fuller-looking, coordinated care
Using the shampoo, conditioner, mask and mist together supports volume, softness, smoothness and protection across the full routine.
Cosmetic hair results vary according to hair type, condition, styling habits, water quality and consistency of use.

Everything to know before your first wash.
Can this replace a professional blow-dry or salon volume treatment?
It can create a cleaner, lighter foundation for fuller-looking hair, but it does not reproduce the styling technique, tools or finish of a professional blow-dry.
Does it permanently thicken the hair?
No. It supports fuller-looking hair cosmetically by removing excess oil and residue and improving the appearance and feel of the lengths. It does not permanently increase hair density or fibre diameter.
Does it require heat activation?
No. Use it as a normal rinse-off shampoo. No flat-iron sealing, processing time or professional equipment is required.
Why choose it instead of an ordinary volume shampoo?
It combines balanced cleansing with hydrolyzed keratin, caffeine, organic rosemary oil, Sodium PCA and Zinc PCA in a COSMOS NATURAL certified formula containing 99% ingredients of natural origin.
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.
