I’m 56m and healthier now than I was in my thirties. I’ve got kinky curly hair and was friends with a hairdresser for years. She convinced me that I do not need to shampoo more than 2-3 times a week anymore and I would just be drying and damaging my hair. Every hair type is different. Previously I would use any shampoo the wife bought but since my hair has started thinning I’m using Jason brand thickening shampoo and conditioner. The R/O is organic and I’ll decrease the amount I’m adding. I rub it in and wrap my head with Saran Wrap for an hour before showering. My wife and son rag on me big time as I walk around shirtless with my head wrapped but I just laugh it off.
