Description +

Kyros is a 25ml hair regrowth serum with a roll-on applicator. It combines four clinically studied ingredients—Rosemary Extract, Redensyl, Aminexil, and Anagain—to fight hair loss from multiple angles. Apply directly to thinning areas like temples, hairline, and crown. Fast-absorbing, non-greasy formula. No pills, no prescriptions.

Clinically Proven Benefits +

Rosemary extract matched minoxidil results in a 6-month clinical study

Redensyl shown to reactivate dormant follicles and increase hair density

Aminexil proven to reduce hair fall by keeping follicles anchored

Anagain clinically demonstrated to extend the hair growth phase

Is this safe to use? +

Yes. Kyros is 100% topical, meaning nothing enters your bloodstream. No hormonal disruption, no sexual side effects like finasteride. All ingredients are naturally derived and clinically tested. Safe for daily use. If you have a sensitive scalp, do a patch test first.

How To Use +
  1. Roll onto thinning areas (temples, hairline, crown)
  2. Let it absorb for 30 seconds
  3. Style as usual—no rinse needed

Use twice daily, morning and night. Takes less than a minute

Frequently Asked Questions

How is this different from minoxidil? +

Minoxidil is a chemical vasodilator that can cause scalp irritation and unwanted facial hair growth. Kyros uses rosemary extract which matched minoxidil results in clinical studies but without the harsh chemicals. Plus we add three other active ingredients that minoxidil doesn't have.

Will this mess with my hormones like finasteride? +

No. Kyros works topically on your scalp only. Nothing enters your bloodstream. No pills, no systemic hormone disruption, no sexual side effects.

How long until I see results? +

Most guys notice less shedding in 2-4 weeks. Visible new growth typically appears around month 3. Full results by month 4. We offer a 90-day money back guarantee so you can try it risk-free.

Does it work on a receding hairline or just the crown? +

It works on temples, hairline, and crown. The roll-on applicator lets you target exactly where you need it.

Will it make my hair greasy? +

No. The formula absorbs in seconds. No residue, no greasiness, you can style your hair right after.

What if it doesn't work for me? +

You get a full refund within 90 days. No questions asked.
