My part kept getting wider. The fix wasn’t another shampoo.

I noticed it in photos first — a little more scalp showing every month. I bought the thickening shampoos, the biotin gummies, the rosemary oil everyone swears by. My ponytail kept getting thinner anyway.

What finally made sense: shedding rarely starts with the strand. It starts at the scalp. A tired, congested scalp slows the follicle down — and oils sitting on top never reach it.

Meridian Roots is a lightweight scalp serum — rosemary, peptides and caffeine — made to wake up a tired scalp and support the look of fuller, healthier hair from the root.

I used it nightly. Around the eight-week mark my part looked less obvious in the same bathroom light I’d been dreading. Not magic — just finally treating the right place.
