i have used this for a long time now and it is amazin..i had a brain anerysim that blew awhile ago and they had to shave my head..it came in VERY slow then the lady at the vitamin store suggested this and i used it about a year and a half it came back really good so i thought i would save money because it looked good again..so.i stopped a couple of months it took NO time and it was thin again so i got back on it..its exspensive but as long as i can i will not stop takin it again..thats why i ordered it this time because of the virus stores r closed..i dont know how much longer i can get it but i will until i cant..my husband fell in feb and broke his back then had a heart attack and waa on life support for awhile now on permanent oxygen at home..will soon be loosin our home like so many others and move to another state to stay with my son for awhile and obviously my husband lost his job thank God we still have our social security it will help but have to have help for awhile..but anyway if ur hair is thin and u can afford to buy this..please do..u will be happy with it..it has really helped my hair and my self asteam..hope i can keep it up luv it
