Is this shampoo suitable for my hair type?

Elfa Pharm THE DOCTOR Shampoo Keratin, Arginine and Biotin is formulated for hair that feels rough, looks dull, or knots easily after chemical or thermal stress. If your hair has been coloured, bleached, permed, or regularly heat-styled, the cuticle layer is likely lifted and porous, which makes strands catch on each other and lose shine. This shampoo addresses that by depositing hydrolysed keratin fragments onto damaged areas, smoothing the surface so light reflects more evenly and combing resistance drops.

It also suits households where shampoo is used daily or on multiple people — the 946 ml salon-size bottle reduces replacement frequency. For very fine or low-porosity hair that gets weighed down easily, you may find a lighter cleanser more comfortable, but for medium to thick, porous, or long hair that frizzes or tangles, the formula’s balance of strengthening actives and light oils (sunflower and peanut oil in small amounts) gives a cleaner feel than heavy masks while still leaving hair manageable.

Use it as the cleansing step in your routine, then follow with a conditioner or mask on mid-lengths and ends if frizz or knotting persists. The shampoo alone won’t replace a deep treatment, but it prevents the cleansing step from undoing the conditioning you apply afterward.
