Let me explain you what hair color is first. Every hair coloring implies chemical reactions with your hair. The process of coloring goes as a chain of following reactions: in the first stage of coloring the hair cuticle is removed to let the color penetrate hair in the second stage. The difference between semi permanent and permanent hair colors is that the first type only minimum amount of color is added and color molecules do not penetrate hair deep so those can be washed away after some shampoos while permanent hair colors volume is bigger and they lighten our hair before adding new color.
Damage to hair cuticle caused by bleaching and chemicals in coloring process is almost inevitable even with hair high lightening. Unfortunately, radical change of hair color is almost impossible with natural hair colors which are the safest way of coloring. Most of natural colors are extracts from herbs and minerals.
One of the most popular natural colors is henna from West Asia and Africa. Henna not only adds beautiful brownish red color to your hair but is also a good natural conditioner. Color you get after using henna depends on your initial color and on how long you kept it on your hair. The best thing about using henna is that it is a natural color, which never damages your hair.
Now let's stop on colored hair advice to avoid mistakes while washing and drying hair. We wash our hair so regularly and it became such an ordinary procedure that we do not pay attention any more to the damage every day shampooing may cause to our hair. There is some colored hair wasing advice that you should remember well. Rinse your hair well before using shampoo, try to wash hair in natural position standing or hanging over the bath.
Never apply shampoo directly to your hair but first lather it up to your hand and only after that apply to hair. Then massage shampoo into your hair carefully with fingertips. Use special shampoo for "frequent use" in case you wash your hair on daily basis. Actually most of modern shampoos are made for everyday use. Nevertheless, it may be useful to get some colored hair advice from your hairdresser and check special shampoos for colored hair in the shops.
As regards question about how frequent you might need to change shampoo, you may never need to if you are using professional one. On the other hand, new water conditions may cause different reaction with your hair, so this may force you to change shampoo. Also climate and even the time of year may affect condition of your hair. As for colored hair drying tips remember not to bring hair dryer close up to your hair and finish setting up your hair style using cold air function.
