A Novel Immune Competent Murine Hypertrophic Scar Contracture Model: A Tool to Elucidate Disease Mechanism and Develop New Therapies

Carnosic acid in rosemary extract may enhance skin repair and promote hair follicle regeneration. It could be used alone or with verteporfin for scarless healing after dermal wounding.

Hair regrowth on wounded and bald skin may be possible by activating the sonic hedgehog gene, leading to hair regrowth in mice. The findings are promising but may not directly apply to humans.

Minoxidil may inhibit collagen synthesis at high concentrations, with anecdotal reports of skin aging but limited research. Dermatologists and other specialists show little interest in studying minoxidil's side effects.

Oleic acid and microneedling are being explored for hair regrowth, but results are mixed. Addressing DHT and fibrosis is crucial, with treatments like finasteride, minoxidil, and scalp massage also discussed.

Microneedling can help with hair loss by inducing collagen if done correctly, but improper technique may cause scarring and worsen the condition. Some users apply dissolved vitamin C before and after microneedling to enhance results.

Microneedling at 0.6mm depth every two weeks showed better hair growth results than using minoxidil alone. Using a derma pen is recommended over a roller to avoid scarring.
