1-Wash and condition your hair. Wash your hair gently, using a thickening shampoo that helps prevent breakage. Massage the shampoo into your scalp lightly and work it down to the ends of your hair, using your fingertips as you go. Don’t bunch your hair up on your head, as that can cause damage. Rinse out the shampoo, then condition with a lightweight conditioner. Rinse the conditioner thoroughly until you can’t feel any residue in your hair.
2-Part your bangs. Bangs are going to save you in a lot of ways when your hair is thin.
First, they create a blunt line, which is the key to the appearance of thickness.
Second, you can style them however you like – straight down or to the side – so your look is as versatile as people with thick hair. Part bangs with your index fingers at the natural part. Let the hair fall into your face and check its wave or curl pattern in the mirror. When you like what you see, use a rattail comb to ensure the part is perfectly straight.
