So you might know that I’m a bit of a hair product junkie and love finding new miracle products, especially if they are cheap! Its a problem that high end hair products are just very expensive and you never know if they are going to work for you, so I have a few tips on where to look for marked down/cheaper products.
I wanted you to know that this weekend I covered faded red dye (to pink) with orange dye and it worked perfectly, I achieved a lovely bright orange.
This was faded adore red with directions tangerine over it.
Other colours that can cover
There are more of course, but I thought this might be helpful!
This post outlines the different types of hair dye on the market for at home dying, and explains some of the chemistry that goes into them so as you will better understand how to use them. I hope you find this informative :) most of it is already in the FAQ and on my original gaiaonline thread, but I thought I would make it more readily available here.
Readily available on the UK market are both semi permanent and permanent hair dyes. These can both be purchased to do at home as well as being available in most salons (which will also be able to offer you a wider range of types of dye). You can also find wash in/wash out dyes that last ‘six’ washes, but often only tint the hair lightly for a couple of washes. Demi-Permanent dyes are those that contain an alkaline to open cuticles, but do not lighten the natural colour of the hair- these are widely used to cover grey.
Permanent dyes to use at home are often referred to as ‘box dyes’ because they come in little cardboard boxes from drug stores. Almost every hair company have their own brand of dye, and there’s no real difference in them other than the shades, though many people have their favourites. Colour shade and staying power always really relies on the individual rather than the whole. Box dyes are not often made to be used on bleached hair, where as semi permanent bright colours are only ever very effective on bleached hair. Box dyes that contain metallic salts SHOULD NOT be used on bleached hair as the reaction will cause unwanted colours!
Permanant dyes work by having a developer that creates the molecules in the dye to shrink as you apply it to your hair so they are able to enter the shaft of the hair easily, after an hour or so, the developer stops working and the molecules grow back to their original size and are unable to then escape.
Merely reverse the developer process by shrinking the dye molecules back to their smaller size, allowing them to become free and dragged from the hair. If the timing is not adhered to, you can easily end up with patchy hair since some of the (anti) developer has stopped working, and the dye molecules are again too large to escape.
Semi Permanent dyes are usually vegetable dyes, made from vegetable extracts and work because they have small molecules that enter the cuticle of the hair, unlike permanent dyes however, there is no developer, the molecules do not change size, so they are able to escape through the cuticle as you wash it. Think of putting a ball in a hole, with permanent dye, developers make a large ball small enough to go through the hole, then the developer stops working and the ball (molecule) grows large again, and so cannot come back out. With veg dyes, the ball stays the same shape throughout.
Hair that has never been coloured is referred to as ‘virgin’. Virgin hair will not take to colour as well as that which has been previously treated because lighteners (for example) open the cuticles and allow the colour to penetrate the hair more effectively.This however also works both ways since once the cuticle is open, hair dye can also be dragged from the hair more easily- some lighteners (as well as many alkaline such as dish soap) and clarifying shampoos open the cuticle a great deal, thus allowing colour to be dragged from the hair. Shampoo always opens the cuticle, but conditioner closes it.
Because of cuticles being closed, virgin hair often holds colour a lot more effectively than that which has been treated.Be aware that box dyes often have agents in them to open cuticles.
I’ve had a lot of questions in the past about putting bright colours on darker hair. I believe that the best way to think about this is as if you are trying to paint. Painting on a white sheet of paper will get you a true and perfect colour. Trying to put the same colour on a black sheet will be dulled- think of your hair in the same way. You can put light colours on dark hair, but will often only be able to see a sheen or hint of the colour you put on.
To remove any confusion, I will quote this site
The outer layer of the hair shaft, its cuticle, must be opened before permanent color can be deposited into the hair. Once the cuticle is open, the dye reacts with the inner portion of the hair, the cortex, to deposit or remove the color. Most permanent hair colors use a two-step process (usually occurring simultaneously) which first removes the original color of the hair and then deposits a new color. It’s essentially the same process as lightening, except a colorant is then bonded within the hair shaft. Ammonia is the alkaline chemical that opens the cuticle and allows the hair color to penetrate the cortex of the hair. It also acts as a catalyst when the permanent hair color comes together with the peroxide. Peroxide is used as the developer or oxidizing agent. The developer removes pre-existing color. Peroxide breaks chemical bonds in hair, releasing sulfur, which accounts for the characteristic odor of haircolor. As the melanin is decolorized, a new permanent color is bonded to the hair cortex. Various types of alcohols and conditioners may also be present in hair color. The conditioners close the cuticle after coloring to seal in and protect the new color.
