Thank you for the advice! I have been feeling "dry," "thinner," and "weak" hair at age 55. I had very thick hair, so I still have a good volume hair even I've lost a lot with aging. "Dry hair"... I watched your videos and am trying some hair oil and better-quality hair treatment/conditioner --- much better feeling :) I looked older when I tried shorter hair (just above shoulder) in my 40s and early 50s...so I have been keeping my hair at medium long length though. Natural + perm wave helps for easy styling :) Keep up with your great work! I am following!
