Roota Review: Does This Roll-On Serum Stop Hair Thinning?

Overview

You’ve probably heard this before, but your hair tells a story.

It’s part of how you show up in the world, and when it starts to thin or shed more than usual, it can feel like you’re losing a little piece of yourself. Maybe you’ve noticed extra strands on your brush, or your once-full ponytail feels smaller.

You try to ignore it, but every glance in the mirror reminds you that something’s off.

Listen, you’re not stuck with this. Hair thinning doesn’t have to be your new normal. Roota, a roll-on serum, is here to help you reclaim that thicker, stronger, healthier hair you’ve always wanted.

Does it work? What is it made of? Should you give it a shot? We have the answers to these and more. Read along.

What Is Roota?

Roota is a roll-on hair growth serum designed to tackle thinning hair. This clinically-backed solution works directly on your scalp to block excess DHT, the hormone often responsible for hair loss. Roota helps reduce shedding, promote regrowth, and strengthen your strands.

What especially stood out for us is Roota’s simplicity and effectiveness. The precision roll-on applicator makes it easy to target thinning areas without mess, and the lightweight formula absorbs quickly, leaving no greasy residue.

How Does Roota Work?

Roota works by addressing excess DHT (dihydrotestosterone) buildup on the scalp, which is believed to be what actually causes hair thinning^[1].

DHT shrinks hair follicles, leading to weaker strands, increased shedding, and eventually, halted growth. Roota’s roll-on serum blocks this hormone directly at the scalp, giving your follicles the chance to recover and regrow.

But it doesn’t stop there. Roota boosts microcirculation, ensuring your scalp gets the oxygen and nutrients it needs to support healthy hair growth. By reactivating dormant follicles and extending the hair growth phase, it helps you see visible results like reduced shedding and new baby hairs in just weeks^[2].

Roota Ingredients – Are They Safe & Effective?

Here’s what each ingredient brings to the table, and the science behind each;

Rosemary Oil

Rosemary oil is a natural powerhouse for hair growth. A 2015 study shows it’s as effective as minoxidil, a common hair loss treatment, but without the side effects.

It works by improving scalp circulation, delivering nutrients to hair follicles, and reducing DHT buildup, which often causes thinning. Its anti-inflammatory properties also soothe the scalp, creating an ideal environment for healthy hair^[3].

Biotin (Vitamin B7)

Biotin is essential for keratin production, the protein that forms the structure of hair. It strengthens strands, reduces breakage, and supports overall hair health. While biotin deficiencies are rare, supplementation can help improve hair quality, especially in cases of brittle or thinning hair^[4].

Peptides

Peptides are short chains of amino acids that play a crucial role in hair health. They stimulate collagen production around hair follicles, which strengthens the follicle structure and improves elasticity.

By extending the anagen (growth) phase of the hair cycle, peptides encourage denser, healthier hair growth. They also help repair damaged follicles, making them an essential ingredient for long-term hair resilience^[5].

Caffeine

Caffeine isn’t just for your morning coffee—it’s a powerful stimulant for your hair follicles. It works by increasing microcirculation in the scalp, ensuring hair roots receive an adequate supply of oxygen and nutrients. Caffeine also counteracts the effects of DHT, the hormone that weakens hair follicles and leads to hair loss.

A 2012 study showed that caffeine can penetrate the scalp and stimulate dormant follicles, promoting faster and stronger regrowth^[6].

Redensyl®

Redensyl® is a clinically tested compound designed to target hair follicle stem cells. A recent 2015 study found that it reactivates dormant follicles, increases hair density, and reduces shedding.

Redensyl® stimulates the division of hair follicle cells and improves their metabolism, so you get faster and more robust hair growth^[7].

How to Use Roota?

Step 1: Apply Directly to the Scalp
Start with clean, dry hair. Part your hair to expose the areas where thinning is most noticeable. Using the roll-on applicator, gently glide Roota directly onto your scalp. Focus on the roots, as this is where the serum works best. Avoid applying it to the hair strands.

Step 2: Massage for Better Absorption
After applying, use your fingertips to massage the serum into your scalp for 1–2 minutes. This step is crucial; it helps the serum penetrate deeply and stimulates blood flow to the follicles. Be gentle to avoid irritating your scalp.

Step 3: Stick to a Daily Routine
Use Roota once a day, either in the morning or evening, depending on your schedule. There’s no need to rinse it out, as the lightweight formula absorbs quickly without leaving residue.
