Better hair quality

Have any of you noticed stronger or improved hair quality since quitting? I’ve read that caffeine can reduce blood flow to the scalp which I believe could be bad for hair growth.

Caffeine can also be negative for nutrient absorption, we need certain nutrients for hair health.

Caffeine raises cortisol and stress hormones can weaken hair. Any anecdotal advice would be great. I am currently trying to kick my sugar free monster addiction 😂 wish me luck!
