About us & our products
What is AVLIN?
AVLIN is a scalp-care brand focused on simple, targeted routines for women experiencing visible thinning, shedding or changes around the hairline, part, temples and crown.
How do I use the Korean Hair Growth Serum?
Remove the cap, rotate the applicator into the open position and gently brush it directly over the areas of your scalp you want to target. Leave the formula in and allow it to absorb. For best routine consistency, use once daily.
Can I use it on any hair type?
Yes. The applicator is designed for direct scalp application and can be used across different hair types and textures.
How long does one bottle last?
This depends on how much of your scalp you treat and how much product you use per application. Targeting a smaller area such as the hairline will generally make a bottle last longer than treating the full scalp.
