Hair Health · Evidence Review
Thinning hair in your 40s? It's starting earlier than you were told.
A certified scalp specialist on why hair quietly begins to thin in your 40s, years before menopause, and a plain review of the five supplements worth considering.
The short version
- Perimenopause starts in your 40s, not at menopause. Estrogen begins swinging and dipping years early, and hair is one of the first places it shows.
- Shampoos and serums can't reach a hormonal or nutrient cause. A complete vitamin and mineral blend, taken daily, can support it from the inside.
- Of the five reviewed, WEEM was the most complete and the best value to start now, while you have the most hair to protect.
You noticed it slowly, then couldn't unsee it. A part that's a little wider, a ponytail that wraps one more time around the tie, more strands in the brush than there used to be. You're probably thinking you're too young for this. You're not imagining it, and you're not alone. This is exactly when it tends to begin.
Why it happens
None of it is your fault, and none of it is your shampoo. Because the change is happening under the skin, the fix has to come from the inside, by feeding the follicle what it's no longer getting. Not a mega-dose of biotin on its own, which is overhyped, but the full blend working together: the vitamins and minerals like zinc that hair is actually built from, taken every day. The thinning you're seeing now is the easiest it will ever be to get ahead of, and waiting only loses ground.
