Welcome to the forum. You might like looking at a member's grandmother's recipes and haircare. I've always loved going over that thread here.

Historical hair care is so interesting although I'm pretty sure my hair would hate not having conditioner. But, I try to incorporate what works for me like stretching washes and using a finer comb to get out gunk. Have you seen any of Longhaired Flapper's recipes or Snappy Dragon's historical hair experiments (both on YouTube). I recommend them.
