I finally got my volume back at the roots after years of thinning. My husband immediately noticed the difference!
How To Use
How To Use
Turn the brush head to the ON position. Glide it along your part line, hairline, and scalp with a soft touch. Focus on thinning spots, wider parts, or dryness and flakes.
For the best scalp care and fuller hair, use it in the morning and at night. You can also use it anytime your scalp needs a cool refresh. Massage with the brush tips for about a minute. This helps boost absorption, so no rinsing is needed.
This gentle formula calms and nurtures a healthy scalp. It works for all hair types: sensitive, color-treated, and gray hair. Menthol gives a quick cooling sensation right after you apply it.
Apply the serum to your temples, crown, or hairline for targeted care.
Twist the brush head back to OFF after use to lock the dispenser. Store in a cool, dry place, away from direct sunlight.

Testimonials
-
"My dermatologist suggested PRP injections at $600 a session. I tried this first — 3 months in, the thinning at my crown has filled in and I never booked the appointment."
-
"After one month the difference was obvious — my part doesn't look sparse anymore and my hair has its bounce back. The brush puts it right on the scalp instead of just coating the strands. I've already told my sister and two friends."
-
"This serum leaves my scalp feeling fresh and my hair looking fuller every morning. It's now part of my daily routine!"
-
"Results that speak for themselves. My hair feels thicker, and that widening part is a thing of the past. I've finally found my 'holy grail' for confidence!"
-
"My part line has filled in so much. I finally feel confident wearing my hair up again!"

Perfect for targeting widening parts, visible scalp, and areas of shedding or flaking. The 38-tip brush lets you apply it precisely — just glide it along the areas you want to treat.
For scalp use only — avoid contact with eyes.
Does it have a scent?

No added fragrance. Growy has a light, fresh herbal scent from its natural eucalyptus oil and menthol — a clean, cooling aroma that fades quickly after application and won't clash with your usual hair products or perfume.
