Frequently asked questions

Questions? We’re here to help.

When will I start seeing results?

Most users notice scalp vitality and reduced shedding within 4–8 weeks. Visible density improvements typically follow with consistent weekly use.

How do I use the GRWOOTS® Micro-Infusion System?

Use once weekly on clean scalp. Fill the chamber with serum, prime for 1–2 minutes upside-down, stamp targeted areas 30–50 times, massage gently, leave on 15 minutes, then rinse.

Does micro-infusion hurt?

You may feel light pressure or tingling, not pain. Designed for comfort and controlled depth.

Can I use this with hair serums or growth products?

Yes, but GRWOOTS® serum is formulated for micro-channel delivery. If layering other products, wait 24 hours.

Is this the same as microneedling?

No. Microneedling rolls and tears skin. GRWOOTS® creates controlled micro-channels for targeted serum infusion, precision depth, and cleaner delivery.

Do I need a new needle head each time?

We recommend a fresh head for each weekly use for hygiene and precision. Never reuse if needles appear damaged.

Can I use GRWOOTS® if I have sensitive scalp?

Yes, the system is engineered for gentle application. If irritation occurs, pause use and consult a dermatologist.

Is this safe for women and men?

Absolutely. GRWOOTS® is formulated for all hair types and genders.

Do I need to refrigerate the serum?

No. Store in a cool, dry place.

Can I use this with medical treatments like Minoxidil?

Yes, but apply topical medications the next day unless otherwise directed by a healthcare provider.

Is this system dermatologist reviewed?

Yes. Developed with trichology and dermatology input for safety and scalp tolerance.

Do you offer a trial or guarantee?

Try GRWOOTS® risk-free for 30 days. If it’s not for you, return unopened serum vials.

Do you ship internationally?

Yes, international shipping available at checkout.
