Kerastase Bain Prevention System Pro Actif Anti-Hair Loss & Scalp Fortifying Shampoo for Thinning Hair & Weakened Strands 200ml
Hair that feels finer and flatter than it used to has a lot of possible causes, and a shampoo will not sort out most of them. What a fortifying wash can do is look after the scalp and cut down the breakage that makes the problem look worse than it is.
That is where the 200 ml Bain Prevention sits. Kerastase built it around the scalp as much as the strand, with a gentle cleanse that clears sebum and residue, and a conditioning side that leaves fine, weakened lengths feeling stronger and less likely to snap when you brush. Less breakage means more of the length you have already grown stays on your head.
Tagged for 2a through 3c. Treat it as the first step of a routine rather than a standalone answer, and if your hair density is changing quickly it is worth speaking to a GP or trichologist alongside whatever you wash with.
On the practical side, this one wants to go on the scalp rather than the lengths. Massage it in for a minute or so, rinse, then keep any conditioner well away from the roots so nothing weighs down hair that is already looking flatter than you want it to.

Application tips
The scalp is the target here, so keep the product where it can do its job.
Wet the head through, then apply a small amount directly to the skin in several places rather than in one lump. Massage with flat fingertips for a minute or so, moving the skin over the skull rather than raking through the hair. Rinse thoroughly. Condition the lengths separately if they need it, keeping it off the roots.
Results
A clean scalp is the whole aim of a wash like this. Sebum, dust and old product come away, and the skin feels comfortable rather than tight.
Fine hair behaves better once it is genuinely clean. It dries with more lift at the root and looks fuller through the mid-lengths, and strands feel less fragile between the fingers, which shows up as less breakage at the brush. The 200 ml bottle lasts because it takes very little per wash.
