I've been on a long and often frustrating journey dealing with hair loss and noticeable thinning, especially around my temples and part line. It's truly disheartening to see more hairs in the drain or on my brush than usual. I've tried countless shampoos, supplements, and even home remedies, but nothing seemed to truly make a difference. That's why I was so keen to finally get my hands on the Kérastase Genesis Serum for hair loss. I'd heard so much buzz about it, especially its key ingredient, Aminexil. What really piqued my interest, and what the research I did confirmed, is how Aminexil is supposed to work at the root of the problem. It's not just a superficial fix. From what I understand, it targets something called perifollicular fibrosis. Basically, collagen can harden around your hair follicles, almost suffocating the root and leading to premature shedding. Aminexil helps to soften this collagen barrier. Imagine your hair root having a stronger anchor to your scalp – that's essentially what it aims to do. By improving this anchoring, your hair can stay rooted longer, complete its natural growth cycle, and maintain better density. The promise of stronger, thicker hair really resonated with me, as my main concern has been the overall thinning and fragility. This scientific explanation gives me more confidence than just generic 'hair growth' claims. My first impressions after applying the Kérastase Genesis Serum have been positive. It has a surprisingly light texture, not greasy at all, which is a huge plus for someone like me who washes their hair every other day. The application is straightforward: usually about four pipettes worth, applied section by section directly onto the scalp. I gently massage it in with my fingertips to ensure even distribution and stimulate blood flow, which I've read can also aid absorption and hair health. It absorbs quickly, and I haven't noticed any residue or stickiness, which often happens with other scalp treatments, making it easy to use daily without weighing down my hair. The scent is also quite pleasant and subtle, not overpowering, which is important for daily use. I'm planning to use this consistently, twice a day, as recommended, to truly gauge its effectiveness. I'm going to be paying close attention to a few things: Are there fewer hairs falling out in the shower and when I brush? Does my hair feel stronger and more resilient when I style it? And most importantly, do I start to see a visible improvement in the overall density and a reduction in the appearance of thinning hair? I’m hopeful this isn't just another temporary fix but a genuine solution to strengthen my hair from the roots. I've even started taking weekly photos to track my progress objectively. While early days, I'm optimistic this Kérastase treatment will live up to its claims. I'll keep you updated on my progress and share my honest thoughts on whether it delivers on its promise of reducing hair fall due to breakage and increasing hair fullness. Wish me luck on this journey to healthier, fuller hair!
