Once again, I'm sharing a short article titled Shampooing More Often, from Woman's World, 6/17/10:
Basically, Gary S. Hitzig, M.D. , a hair transplant surgeon says
1. washing your hair less often makes hair more brittle.
2. that a by-product of testosterone called 5DHT can build up on the scalp, causing hair to grow out weak and easily be broken.
He recommends gently washing every 24 to 48 hours to keep 5DHT levels low.
