Reverting to Chemical Hair Dyes after Henna
If henna isn’t for you and you want to get back to commercial hair dyes, it’s fine to backtrack within the first two to three weeks. Ideally, however, we recommend that you wait two months or longer after your last henna application. If that is too long for you then aim for at least one month. If you’re not keen on henna, for whatever reason, the sooner you decide the better. The longer you leave it and the more you use henna, the more the henna colour will build up in your hair and the harder it may be to get good colour take with your commercial hair dye.
How long henna lasts varies considerably from person to person. Henna has the potential to be a permanent hair colour, especially on grey hair. Over time henna will fade, but once you’ve used henna, especially more than once, you will have to think seriously about allowing time for it to grow out.
If you’re desperate to tone down a henna hair colour, try saturating your hair with yoghurt and leave it in for up to 20 minutes before washing it out, and shampoo your hair as much as possible. Don’t use hair conditioner. After intensively washing your hair, you’ll need some cassia obovata to restore your hair to its shining glory. Cassia obovata is the best hair conditioner for damaged hair.
If you don’t want to wait for two months before going back to chemical dyes, we recommend strand test with your normal hair dye before applying it to the entire hair to see how it takes. The worst that’s likely to happen if you use the hair dye too soon is that you’ll have wasted a pack of hair dye if the colour doesn’t take. It’s likely, however, that within two to three weeks of your last henna hair dye application you will get good colour take from commercial hair dye.
Remember that henna’s natural function is to act as a barrier to things which are harmful to your hair.
