Finasteride can cause scalp itch and inflammation, possibly due to DHT changes, but these effects are often temporary and part of the shedding phase. Consistent use of finasteride may show results after 6 months, with potential hair regrowth and slowed hair loss.
Scalp massages may help with hair loss, but results require significant time and effort, and benefits stop when massages stop. Some users combine massages with topical minoxidil and finasteride for better results.
Sunburns on the scalp can cause permanent hair loss, especially for those using Tretinoin or Tacrolimus. Wearing UPF 50+ hats is recommended to protect against UV radiation.
