Herbal Hair Colour Frequently Asked Questions
Can I use your hair colours on top of chemically dyed hair?
Many customers have successfully used our hair colours on top of chemical dyed hair, but you have to be careful because it will affect the way the colour takes and the colour could be unpredictable and not what you expected. The following points should be considered:
1. It is best to wait 5 or 6 weeks after a chemical dye.
2. It is important to strand test the chemical dyed hair first to check that the colour is what you want before putting on your full head of hair.
3. If your hair is bleached it is especially important to strand test because bleach changes your hair structure and makes it more porous and so the colour can appear more brassy or go a strange colour.
Can I use chemical dye after using your hair colours?
It is usually OK to use a deposit only, darkening chemical hair dye on top however you still have to careful that the colour is as you would expect. It is best to wait 5 or 6 weeks after the natural hair colour and strand test to check the colour is what you would expect.
It is not recommended to use chemical bleach on hair that has been dyed with a herbal hair colour containing indigo, i.e. black or brown shades or indigo itself, unless it has faded or grown out. This is because bleach will not remove indigo so you may possibly be left with a bluish colour. If you do want to try it please strand test first.
Can I used your hair colours if on chemotherapy or pregnant?
During chemotherapy or pregnancy, we would advise you must check with your doctor if it is Ok for you to use them. Our hair colours are quite different to chemical dyes as they are all natural and henna based and usually doctors are fine with them but it is always good to check in case your condition is different.
If you would like to show your doctor the full ingredients list of the products these are on the corresponding product pages on the website, on the packet, or alternatively we can send you a document listing the ingredients of all the hair colours we sell.
Are your hair colours permanent?
The longevity of the hair colours depend upon which shade you use and how porous your hair is. For example the hair at the roots tends to fade more quickly than the hair at the ends which is more weathered and therefore more porous.
In terms of shades, the red shades are virtually permanent. The brown or black shades tend to last on average about 3 to 4 weeks on the roots, but they can become permanent on porous areas of your hair like the longer lengths of your hair.
Do your hair colours cover grey?
Most of our customers use them to cover grey. They will not cover grey as strongly as chemical dyes. Where you have grey hair it will usually be a lighter colour to the rest i.e. if you have some brown and some grey hair the grey hairs will usually come out lighter than the brown hair.
Can you lighten your hair with your hair colours?
No they will not lighten your hair as they do not contain peroxide
Can I use your hair dyes if I am allergic to chemical dyes?
Our hair colours are quite different to conventional chemical dyes. They are natural and henna based without PPD, peroxide, ammonia resorcinol or any other nasty chemicals, however people can sometimes be allergic to them. This is the same as with many natural products, such as nuts or strawberries, that people may have allergic reactions to even though they are only natural.
To be sure of whether you will react to a hair colour it is best to perform a patch test 48 hours prior to putting the product on your scalp. To do a patch test, put a small amount of dye on the inside of your elbow. If any reaction occurs (itching, flakiness, redness) you may have a reaction to the hair colour.
What is the best shampoo to use on coloured hair?
Like our products, we would recommend using a gentle, organic shampoo, like the Gentle Herb Shampoo from Odylique.
