For a change in hair colour that you don't want to be permanent, you can use semi permanent hair dye. Some of the colours and dyes in this range are recommended for hairdressing professionals and will show as restricted to trade purchasing. Other semi permanent dyes and colours can be used at home by carefully following the directions for use. For hair colouring effects like streaks, a steady hand is needed and you may want to think twice about doing streaks on your own. It can be difficult to reach the back part of your head and you may miss some spots. A professional will always do a better job but if you are confident in your skills you can give it a go. Semi dyes will last you roughly a maximum of 8 washes. The semi permanent nature even allows you to get creative and try a wild colour such as hot pink or an electric blue. It is important to note that some of these dyes will require you to lighten your hair. If the base colour is darker, you won't be able to effectively see the colour transformation of neon type colours. Instead, they may appear as a dark blue. Your hairdresser will be able to assist you in lightening your hair colour if needed.
How Semi Permanent Hair Dye Works
The way these direct dyes work is via particles of the colour molecules entering the hair's cuticle. The dye is unable to deeply penetrate the hairs cortex as they are so small, so the dye will rinse off after a few shampoos but can last up to 8 washes. Semi permanent dyes are less harmful to har as they are unable to change the hair's structure, so very minimal damage or irritation is caused. For the most effective grey coverage, a permanent hair dye is recommended. If you have any questions about the right products for you, our hair colour experts are always happy to help.
