Hey guys, saw Tabatha Coffey on Dr. Oz the other day.
She suggests Viviscal (a vitamin supplement) for thinning hormonal hair, it promotes growth and strength. $50 for 60 tablets in most drug stores. Not suggested for balding. Good for hair thinning due to stress or lack of hormones.
If you have dull, grey hair, Aveda makes Blue Mlva which is a violet shampoo. Violet/blue is opposite yellow on the color wheel which means that it will neutralize the brassy, orangey yellow tones.
For brittle and dry hair, try Joico K-Pak Revialuxe $22 (which I can ates too) as a hair treatment. You can find it at Ulta...loooove this product!! Use it up to 3 times a week for dry hair, and once a week for maintaining hair health.
