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:
- Shortened growth phase (anagen cycle)
- Thinner, weaker hair shafts
- Increased shedding and breakage
- Wider parts & receding hairline
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.

How to use Roota Hair Growth Serum for maximum impact
STEP 1
Targeted application
Gently part your hair to expose thinning or sparse areas where support is needed most.
STEP 2
Apply directly to the scalp
Use the roller tip to evenly distribute the serum onto your scalp. Massage lightly with your fingertips for 1–2 minutes to boost absorption and circulation.
STEP 3
Let the actives work
Leave the serum in – no rinse needed. Roota's lightweight formula absorbs quickly and won't leave any residue or grease.
STEP 4
Stay consistent
For best results, apply once daily (morning or evening). Consistent use helps awaken dormant follicles and strengthen new growth over time.
