Skin Rejuvenation and Resurfacing

OP injured their temple using derma rolling and tretinoin, causing peeling and potential hair follicle damage. Users suggest the injury might be permanent, possibly resulting in scar tissue where hair won't grow.

The user is using a combination of microneedling, minoxidil, tretinoin, scalp massages, and red light therapy to address hair loss, with a focus on the hairline and temples. They emphasize the importance of scalp massages and have seen regrowth, attributing success to their comprehensive routine.

Tretinoin and microneedling both enhance hair growth through different mechanisms, with microneedling being considered safe for long-term use. Optimal microneedling needle length varies, but 0.8 mm is suggested for hair growth, and a Dermastamp is recommended to avoid skin damage.

The user has been using minoxidil for over a year with little success, added tretinoin cream, and is considering adding red light therapy. They are advised to use moisturizer to counteract skin sensitivity from tretinoin.

Tretinoin can irritate seborrheic dermatitis, but using it with a moisturizer on calm skin may help. Parallel Health's skin microbiome testing and phage therapy are suggested for persistent issues.

A new treatment using dermal sheath cup cells may regrow hair and could require repeat treatments every 8 years. Users discuss ongoing trials and plan to use finasteride and minoxidil until the treatment is available.
