Understanding Hair Thinning
Seeing more scalp or a widening part? Excess DHT may be involved
When DHT (dihydrotestosterone) accumulates on the scalp, it can affect hair follicle size, leading to progressively thinner, shorter strands. Scalp inflammation and reduced blood flow may also shorten the growth phase and limit nutrient delivery to the roots — contributing to increased daily shedding and visible thinning along the part, edges, and crown.
How excess DHT can affect hair:
- Shortened growth phase (anagen cycle)
- Progressively thinner, weaker hair shafts
- Increased shedding and breakage
- Wider parts and gradual hairline changes
This process can begin as early as your 30s and is common among women experiencing postpartum changes, PCOS, or perimenopause. Many people don't realize the root cause until thinning becomes more visible.
The good news: understanding the mechanism is the first step. Roota was formulated specifically to address these root causes — not just the visible symptoms.

The Roota Approach
A clinically supported roll-on serum designed to reactivate dormant follicles
After years of scalp science research, trichology experts developed Roota to address the underlying causes of hair thinning. Its precision applicator delivers high-potency actives directly to the roots — non-greasy, fast-absorbing, and suitable for sensitive scalps. No prescription needed. No dependency concerns. No harsh chemicals.
🌱 Follicle Reactivation Complex
Combines caffeine, biotin, and Redensyl peptides to help reawaken dormant follicles and support a longer growth (anagen) phase. Studies have shown increases in hair density of approximately 17% over 12 weeks.
🌿 Botanical DHT Shield
High-potency rosemary extract helps address excess DHT at the scalp. Independent research has compared its effectiveness to 2% minoxidil, without the typical irritation or dependency concerns.
🧘 Inflammation Control Complex
A scalp-soothing botanical blend helps calm micro-inflammation, which may support a longer growth window and more comfortable daily use — especially for sensitive scalps.
⚡ Microcirculation Booster
A caffeine-powered formula combined with the cooling roll-on applicator helps promote better microcirculation — improving oxygen and nutrient delivery directly to the follicles.

What's Inside
5 active ingredients behind Roota's formula
A science-supported blend targeting DHT, circulation, and the hair growth cycle to help reduce shedding and support new growth over time.
FORMULATED WITH CLEAN, PLANT-BASED ACTIVES — NO HARSH CHEMICALS, PARABENS, OR ARTIFICIAL FRAGRANCES.
Rosemary Oil
A natural DHT-reducing ingredient that may help stimulate dormant follicles and support scalp circulation. Research has shown it can support new hair growth and help reduce thinning over time.
Biotin (Vitamin B7)
An essential vitamin for healthy hair structure. Biotin supports keratin production, which may help reduce breakage and improve overall strand resilience.
Peptides
Clinically studied to support the hair growth cycle by strengthening follicles and promoting collagen and elastin production around the root for lasting density.
Caffeine
Energizes hair roots by promoting microcirculation and helping to counteract the effects of DHT on follicles. Supports nutrient and oxygen flow to the scalp.
Redensyl® & AnaGain™
Two award-winning, clinically tested complexes that target stem cells and dermal papilla cells — supporting natural hair growth reactivation and visible density improvements over weeks of consistent use.
Application Guide
How to use Roota for best results
Step 1
Targeted Application
Gently part your hair to expose thinning or sparse areas where support is needed most.
Step 2
Apply Directly to Scalp
Use the roller tip to evenly distribute the serum. Massage lightly with fingertips for 1–2 minutes to boost absorption.
Step 3
Leave the Actives to Work
No rinsing needed. Roota's lightweight formula absorbs quickly and leaves no residue or grease.
Step 4
Stay Consistent
Apply once daily (morning or evening). Consistent daily use is key — it allows the actives to work cumulatively over time.
