Safe and effective with no mess.
I’m a 68 year old female and have used the Thermadome EVO LH40 helmet 422 times with positive results. My hair was thinning from menopause and breast cancer treatments. I see new hair growth and gradual improvement over time. The Thermadome website offers helpful information on scalp health and how to improve the scalp to facilitate better hair growth. Customer support has been excellent. I am very happy with the helmet and highly recommend giving it a try.
