How To Wash Hair Extensions With Purple Shampoo. Brush with a bristle brush. Let it air dry completely.
Although purple shampoo will not dye your hair, you may notice some lilac tints after you wash if it's too strong. If the purple residue in your hair is pretty light, a clarifying shampoo may do the trick! How often should you use purple shampoo?
Alternate using it with color safe shampoos—or mix them together for less violet deposit.
Apply shampoo liberally to your hair and let it sit for 1 to 5 minutes. Keep in mind that purple shampoo isn’t intended for daily use. Apply the clarifying shampoo to your hair just like regular shampoo, lather it up for a few seconds with your fingertips, and rinse it out. Start by using once a week and build up if needed.
