What is Larens Hair Repair Shampoo?
Hair Repair Shampoo is a repair shampoo for all hair types from the Larens line (WellU Group), built on the same base as the entire cosmeceutics range — Biopeptide Complex and Nutrivi water. This isn't a typical shampoo that just cleanses and adds shine. The Hair Repair formula works on three levels simultaneously: it cleanses the scalp, rebuilds hair structure, and revitalizes follicles.
What's particularly important is what it doesn't contain: the shampoo is sulphate-free, meaning it contains no SLS (sodium lauryl sulfate) or SLES (sodium laureth sulfate) — sulphate foaming agents that form the base of most mass-market shampoos but can dry out the scalp, damage the hydrolipidic barrier, and harm hair structure with long-term use.
A sulphate-free shampoo foams less than conventional shampoos — that's normal, and doesn't mean weaker cleansing. The absence of harsh cleansing agents is especially important for scalps prone to dandruff, itching or irritation.
Key ingredients — what does what
The core of the formula — follicle revitalization
Marine collagen peptides from Biopeptide Complex penetrate directly into damaged areas of hair structure. They have energizing properties — stimulating follicles to produce longer, thicker hair shafts. Hexagonally-structured Nutrivi water facilitates the transport of active ingredients deep into the scalp.
Rebuilding hair's mechanical structure
Keratin is the structural protein that makes up hair (about 95% of its mass). In the shampoo it acts as a "gap filler" — penetrating cracks in the damaged hair shaft and filling them, restoring smoothness and elasticity along the full length. It contains sulphur, which additionally shows antifungal action on the scalp, helping with dandruff.
Keratin also protects hair from the damaging effects of oxidizing agents (dyes, bleaches), perming, and UV rays and wind — acting as a protective shield.
Supporting growth and antioxidant protection
Vitamin A (retinol) accelerates the cell renewal cycle and supports proper keratin formation. Vitamin E, as a strong antioxidant, protects the capillaries that supply hair with nutrients — dilating them, which improves oxygenation of hair follicles. Biotin (vitamin H/B7) is the most extensively studied ingredient for hair and nail health — it strengthens follicles and stimulates growth. Vitamin B5 (panthenol) moisturizes and smooths the hair cuticle.
Shine, detangling, scalp blood flow
Smooths hair and adds shine, making it easier to detangle. Accelerates hair growth by improving scalp blood flow and strengthening follicles. It also acts as a natural emollient — preventing the hair shaft from drying out during washing.

| Dandruff, scalp itching | Keratin (sulphur) + Biopeptide Complex | Antifungal and soothing action |
| Hair loss | Biotin + vitamin E + Biopeptide Complex | Strengthening follicles, improving blood flow |
| Damage from UV and wind | Keratin (protective shield) + vit. A, E | Antioxidant protection and regeneration |
How to use Larens Hair Repair Shampoo?
Apply the shampoo to wet hair and scalp, gently massaging with fingertips for 1–2 minutes (massage stimulates blood flow to the follicles). Rinse with warm (not hot) water. For very damaged hair, you can leave the shampoo on for 2–3 minutes before rinsing — longer contact gives the peptides more time to penetrate.
You can complement the shampoo with a treatment: dissolve 1 tablespoon of Larens Repair Gel (a collagen-peptide gel) in 1 litre of warm water and use it as a post-wash rinse — an intensive repair treatment recommended 1–2 times a week.
External hair care (shampoo) combined with internal supplementation (Nutrivi Glowin'UP with marine collagen and biotin) works on hair from two directions. Biotin from Glowin'UP supports keratin production from within, while Larens shampoo complements it externally at the shaft structure.
