If your hair is already darker than natural light, you should consider using a concealer along with the purple dyeing. This will help camouflage the purple hair tint so that your natural locks do not become obvious. Also, applying a deep conditioning conditioner to your locks right before you try the coloring will help them grow back a lot faster after the dyeing. After the conditioner, you should always use a high-quality spray hair enhancement product to further fortify your locks.
If you are looking for a really good match, try using semi-permanent hair color. These dark hair colors last anywhere from one to three months. Semi-permanent dyes are cheaper and require only one wash with the semi-permanent shampoo. Semi-permanent dyes are definitely a great option for people who are not willing to spend an excessive amount of money on a new shade of hair dye.
