Hair coloring cosmetics are useful to people with thinning hair to mask the discrepancy between the color of your hair and your scalp, which offers the appearance of fuller hair. The most common form of scalp coloring treatments come in the form of liquid paints or colored lotions. However, depending on your skin sensitivity and lifestyle, heavy powder-based products are also viable solutions for a colored scalp.
Pick a scalp dye that matches the color of your hair. Avoid purchasing products from pictures that you see online, if possible, as it is important to see the color next to your hair. Consult your hair dresser for guidance on selecting the right color for your hair, if necessary.
Read the ingredients on products that you are considering as some chemicals may irritate your skin. For example, avoid lye and other harsh chemicals that damage your skin. Check if you are allergic to the dye by applying a small amount to the skin behind your ear. Allow the dye to set in for a day and monitor for skin irritation or flaking.
Shampoo and condition your scalp to help it prepare for coloring. Use your finger to apply a 1-inch-wide layer of petroleum jelly around your entire hairline to help slow any spilling dye.
Stand in front of a mirror while you work. Comb your hair away from the thinning area, if necessary. Make a clear path to your scalp. Read the label of your product for specifics on application. Apply the appropriate amount of dye to the included applicator swap or sponge.
Wipe your scalp with the applicator with firm, even strokes. Work in sections as wide as the applicator tip. Do not squeeze the swab or sponge against your head as this may expel dye too quickly, causing spillage.
Repeat Step 4 and Step 5 until all areas of your head are colored to your liking. Remove the petroleum jelly and excess dye around your scalp with a soft, dry cloth.
