Re: PABA for gray hair

where can I buy paba. how do I apply it. and how long does it takes to see changes. My hair is mix gray with brown now because I colored it.. Do I have to wait until the color chemical I use wash away before using paba? I have being using colloidal copper for about one month but I can NOT see much difference and I don't know if it is because my hair has chemical colored product on it. any help will be very much appreciatte it. Thank you so much. Blessings. Eagle4 Tweet
