What is Astelle PDRN Scalp Renewal Brush Serum?
It is a targeted scalp serum with a built-in brush applicator designed to nourish the scalp, massage the roots, and support fuller, healthier-looking hair.
Where should I apply it?
Apply directly to the scalp, focusing on areas such as the hairline, part line, crown, or other areas where hair appears less dense.
Will it make my hair greasy?
Astelle is designed as a lightweight scalp treatment. The targeted brush applicator helps place the serum directly on the scalp instead of coating the lengths of your hair.
Do I need to rinse it out?
It is designed as a leave-in scalp treatment. Follow the directions provided on the final product packaging.
What are micro-spicules?
Micro-spicules are extremely small structures used in advanced skincare and scalp-care formulas to provide targeted surface stimulation during application.
When should I expect to notice a difference?
Individual experiences vary. Hair and scalp care typically require consistency, so Astelle is designed to become part of your ongoing routine rather than provide guaranteed overnight results.
Can both men and women use it?
Yes. Astelle is designed for adults looking to improve their scalp-care routine and support the appearance of fuller, healthier-looking hair.

Advanced daily scalp care • Easy brush application
Your hair routine may be missing the most important part.
Your scalp.
If any of this sounds familiar, you're not imagining it — and you're not alone.
A part that looks wider than it used to
More scalp showing in photos and light
Roots that feel flat and weak
Oils and serums that never reach the scalp
Most routines treat the strands. Astelle starts where hair actually grows from — the scalp.
More than a serum. A smarter way to apply it.
A dropper spreads product through your hair. Astelle's brush head parts the hair and lays the formula directly on the scalp — then massages it in.
Serum + targeted brush application, in one step.
Target
The brush head parts the hair and applies serum where it's needed — the scalp and roots.
Massage
Flexible bristles work the formula across the scalp with a cooling, spa-like massage.
Renew
Micro-spicule technology makes it a more advanced scalp-care experience than an ordinary serum.
Three advanced actives
Vegan PDRN
From Korean wild ginseng extract. Supports a revitalized, healthier-looking scalp environment.
Caffeine
Helps energize and refresh the scalp for roots that look and feel more awake.
Micro-Spicules
Ultra-fine spicules gently sweep away buildup and help the formula settle onto the scalp.
A scalp routine you'll actually want to stick with.
One minute, once a day. No rinsing, no residue, no complicated regimen to forget about.

“I was worried it would make my roots look oily, but it feels surprisingly lightweight. The brush makes it really easy to apply directly along my part without getting serum all over my hair.”
Jessica M. — verified buyer
“My part has been the area I’m most self-conscious about, so I’ve been really consistent with this. I love how targeted the applicator is, and my hair has started looking fuller around the roots.”
Amanda R. — verified buyer
“The application is honestly my favorite part. It takes less than a minute, the brush feels really nice on my scalp, and it’s much less messy than the droppers I’ve used before.”
Nicole T. — verified buyer
Better scalp care in about a minute.
Three steps, once through your part lines. No rinsing, no styling changes, no mess.
Turn
Rotate the brush head to the ON position.
Apply
Glide the brush along your part lines and any areas you want to focus on.
Massage
Work the formula across the scalp, then turn the brush head to OFF to prevent leaking.
Before you ask
Will it make my roots greasy?
No. The formula is lightweight and non-greasy — it's designed to absorb into the scalp rather than coat the hair, so roots stay clean-looking.
Do I rinse it out?
No. Astelle is a leave-in scalp serum. Apply, massage, and carry on with your day.
How often should I use it?
For best results, use once daily on a clean scalp. Apply consistently as part of your morning or evening scalp-care routine.
What are micro-spicules?
Ultra-fine spicules that gently sweep away scalp buildup and help the formula settle onto the scalp instead of sitting on your hair. You may feel a light tingle — that's normal.
