community Can microneedling damage existing hair?

in Microneedling 9 upvotes 1 year ago

Microneedling is unlikely to damage existing hair if done with a device using a smaller needle count, like a 9-needle cartridge, and a stamping motion. Hair follicles are deeper than the typical needle penetration depth.

Oil from the neem tree, used in traditional remedies

learn oleic acid

Is there a difference between getting Oleic Acid from oils (like olive oil) versus hair products? Oils on the hair act mainly on the hair shaft and skin surface; eating olive oil is linked with heart health in cohort studies. Neither route has been shown to affect hair growth.
How does Oleic Acid support hair follicle strength and growth? Lab and animal studies suggest oleic acid may help the scalp barrier and hair shaft. No human trial shows that it strengthens follicles or slows hair loss.

learn Cetirizine

How does cetirizine reduce inflammation linked to hair loss? Cetirizine is proposed to lower prostaglandin D2 and raise prostaglandin E2 around hair follicles; three small trials of a compounded 1% topical report modest increases in hair density and shaft thickness, with minoxidil doing better head-to-head. Topical cetirizine is off-label and unapproved for hair loss, and the evidence is too thin to call it effective or safe.
