Application of 3D Scaffold-Free Dermal Spheroids to Investigate Retinol and Retinol Alternatives Mechanism of Action on Extracellular Matrix

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.

Verteporfin followed by retinoic acid improves wound regeneration in mini-pigs. Retinoic acid does not significantly enhance regeneration in rabbits.

Increasing the sult1a1 enzyme on the scalp may improve response to topical minoxidil. The user suggests using a baking soda solution, DMSO, and tretinoin to enhance enzyme activity and minoxidil effectiveness.

Fibrin-based hydrogels support stem cells for hair follicle regeneration, showing promise for treating alopecia and wound healing. They enhance cell viability, maintain stemness, and promote hair and tissue regeneration without teratoma formation.

Using retinol with minoxidil may not be as effective as tretinoin, but retinaldehyde or adapalene could be alternatives. A micro-roller with minoxidil is suggested for better results.

Microneedling and tretinoin may enhance minoxidil absorption for hair loss, but evidence on their effectiveness is limited. Iron supplements and broccoli sprouts are suggested for enzyme activation, but their impact on hair is unclear.
