A deep-cleansing shampoo from Natura Siberica's men's range, for all hair types.
What a deep-cleansing shampoo is for — and when not to use it
A deep-cleansing or clarifying shampoo is a stronger detergent than an everyday one. Its job is to strip: to remove silicone build-up, styling product, heavy oils, chlorine and hard-water mineral deposits that ordinary shampoo leaves behind.
That is genuinely useful, and there are clear signs you need it. Hair that has gone limp, dull and coated for no obvious reason. Products that have stopped working. A scalp that feels heavy or itchy. Hair that will not hold a style. In each case the problem is usually build-up rather than the hair itself.
But it is not an everyday shampoo, and using it as one will cause the problem it is meant to solve. Stripping the scalp thoroughly and repeatedly prompts it to produce more sebum, not less, and you end up in a cycle of greasy hair and aggressive washing. Once every week or two is usually plenty; once a month is enough for many people.
Always follow it with a conditioner on the mid-lengths and ends. A clarified strand has nothing on it at all, which is exactly when it most needs conditioning.
On "for men"
Worth saying plainly: the differences between men's and women's shampoo are overwhelmingly fragrance and packaging. A scalp is a scalp.
There are real average differences — male scalps tend to produce somewhat more sebum, and men on average wash their hair more often and keep it shorter — which is why men's ranges skew towards stronger cleansing and cooling, mint-and-cedar fragrances. That is a reasonable design choice for a common set of preferences, not a biological requirement. Anyone with an oily scalp and product build-up will find this useful, regardless.
Using it
Shampoo the scalp, not the lengths. Two short washes clean better than one long one — the first lifts the oil and product, the second lathers properly. Rinse thoroughly, and condition the ends.
