Seeing more scalp and a widening part? Excess DHT is likely the cause

What’s really driving the thinning you’re seeing

It starts small: extra strands in the shower, more hair on the brush, a ponytail that feels smaller… When DHT (dihydrotestosterone) builds up on the scalp, it shrinks hair follicles, leaving each new hair thinner and shorter until growth stops.
At the same time, scalp inflammation and reduced blood flow shorten the growth phase and limit nutrients reaching the roots. The result is more daily shedding and see-through areas along the part, edges, and crown.

But here’s the alarming part: It can begin as early as your 30s and is common with postpartum changes, PCOS, or perimenopause, often worsening without the right treatment.

Effects of rising DHT on your hair:

You can reverse visible thinning with Roota – a clinically backed roll-on serum built to reactivate dormant follicles without drugs, dependency, or initial hair shedding.

After years of scalp science and research, trichology experts created Roota to treat the cause of hair thinning, not just the symptoms. Its precision applicator delivers high-potency actives straight to the roots, goes on clean and non-greasy, and is safe for sensitive scalps.

Trusted by users and trichologists alike, it’s built for fast, visible change and everyday use. No prescription. No lifetime dependency. No side effects.

Roota's clinically powered formula targets every stage of hair thinning

Six high-impact actives that block excess DHT, extend the growth phase, boost microcirculation, and fortify the scalp, so hair grows back stronger, denser, and visibly fuller.

Follicle Reactivation Complex
Reawakens dormant follicles and lengthens the growth (anagen) phase with caffeine, biotin, and Redensyl peptides, shown to increase hair density by ~17% in 12 weeks.
Botanical DHT Shield
High-potency rosemary extract helps reduce excess DHT at the scalp – shown in studies to match 2% minoxidil without typical irritation or dependency.
Inflammation Control Complex
A scalp-soothing botanical blend helps calm micro-inflammation, supporting a longer growth window and more comfortable daily use, ideal for sensitive scalps.
Microcirculation Booster
A caffeine-powered formula and cooling roll-on application help improve microcirculation for better oxygen and nutrient delivery straight to the follicle.
