Product description

Can I use this serum alongside minoxidil or other hair treatments and products?

OS-01 HAIR can be used alongside other products and medical-grade treatments as well. We always recommend applying OS-01 HAIR first and patch-testing when using other products to ensure the combination of all products works well for you.

Can I use this serum if I have sensitive skin or a sensitive scalp?

Absolutely! OS-01 HAIR was formulated to be safe for sensitive skin and scalps.

Is this serum suitable for all hair types?

Definitely! OS-01 HAIR is suitable for all hair types, including oily hair, and integrates easily into any hair care routine with visible results within as little as 90 days.

Is this safe for use during pregnancy or breastfeeding?

All OneSkin products are free of sulfates, parabens, and phthalates. As always, we recommend pregnant and breastfeeding women consult their physician with any questions or concerns.

Do I apply this before washing my hair or can I leave it on?

Apply 1mL of OS-01 HAIR serum 1-2x daily (AM or PM) directly to your scalp and massage in with your fingertips. Leave on, and do not rinse. For enhanced absorption, use a dermaroller on a clean scalp before application.
