Is it better to paint on dirty or clean hair?

The question of whether to wash your hair before painting is very relevant. It is very difficult to give an unambiguous answer to it. This is due to the fact that earlier hair dyes were quite aggressive and contained a lot of ammonia and heavy metals.

The effect of these substances on the skin and hair led to sad consequences, which is why it was more advisable to dye dirty hair, protected by a thin fat layer. Today, with the advent of more gentle methods of dyeing, the situation has changed a bit, making it possible to dye clean curls without risking damage to their condition.

Whatever the upcoming dyeing method, hair before this procedure is necessary prepare well. For this, the curls are pre-saturated with various beneficial substances and moisturized well. Preparation usually begins a couple of weeks before the event and consists in regular applying nourishing masks, using balms and conditioners.

This is due to the fact that despite the powerful support to the hair roots, the oil forms a microfilm on the surface of the curl and prevents the penetration of color pigment into micropores.

Use folk methods in this case, one should use very carefully and whenever possible only proven cosmetics specially designed for such procedures.Another important step in preparing hair for dyeing is to conduct two tests. The first is in determining the likelihood of allergic reactions on the selected dye. For this, a little diluted product is applied to the skin of the wrists and left for half an hour. If during this time no changes are observed, then the paint can be safely used.

After the first test is successfully passed, it is necessary to conduct a second test. Its essence lies in applying a small amount of paint to a strand of hair and waiting for the result of dyeing. If the resulting shade has met all the requirements, then you can proceed to full staining.

There is no clear answer to this question. It all depends on many subjective factors: the method of dyeing and the composition of the paint, individual characteristics and structure of the hair.

So, mandatory washing of the head is provided in a number of cases.

• If shortly before staining gel, varnish, foam or mousse was applied to the hair, then it is simply necessary to wash them. Otherwise, the remnants of the chemical components of the previous agent may react with the substances of the paint and lead to a completely unexpected result.
• If hair color it is planned to change very often, and this shade is applied for a short time, it is also better to wash your head.
• Locks, which are supposed to be painted in dark colors, it is also recommended to wash. This will make the color more saturated and provide its depth.
• Aesthetic moment. Before going to the salon, many rightly worry that the master will not be very pleased to work with an unwashed head, and therefore prefer to wash their hair at least a day before visiting the hairdresser.
• Most modern toolssuch as tonics, semi-permanent paints, mousses and henna are intended to be applied only to clean hair, so washing your hair before using it is not even discussed. If this requirement is neglected, then the color will begin to wash off after a few days.
• Judging by the numerous reviews, when dye is applied to unwashed greasy hair, the paint is quickly washed away and there is no characteristic shine.
• Application of coloring compounds on clean, slightly moistened strands contributes to a more uniform coloring along the entire length, which is not always possible to achieve when coloring dirty hair.

As discussed above, there are many prerequisites that require washing curls before staining. However, there are several cases in which hair washing is best eliminated.

• Gray hair painting requires application of paint only to dirty hair. This is due to the fact that for painting gray strands, a more resistant paint is required, containing, as a rule, a large number of aggressive components. Their excessive presence can cause irreparable damage to the hair structure, and therefore it is better to dye it on oily hair.

A thin fat film uniformly envelops each hair and reliably protects its structure from destruction. If you wash your hair, then the curls become defenseless before exposure to chemicals, noticeably fade and begin to split.

• Lightening also best performed on a dirty head. This is due to the presence in the composition of decolorizing preparations of high percent peroxide, ruthlessly destroying the hair structure and leading to severe drying of the curls.
• Highlighting the strands are carried out according to a principle similar to bleaching and also requires the presence of a greasy film on the hair. Before the procedure, it is better to refrain from washing your hair for 3-4 days. The period of abstinence from washing is selected individually and depends on the productivity of the sebaceous glands.
• After perming You can dye your hair after 14 days. During this time, the head can be washed only 1 time - a week after curling and, accordingly, 7 days before staining.
• Dry, brittle and damaged hair are also one of the reasons why it is better to refuse to wash your hair before painting. So that the coloring pigment is correctly distributed and does not harm the hair, the hair should not be washed for at least 2-3 days.
• Problem and dry skin also requires painting on dirty hair. Otherwise, the scalp loses its protective fat layer and begins to itch and peel.

However, there is also opponents of dyeing dirty hair, motivating their beliefs that at present there are a large number of modern drugs that do not have a detrimental effect on the hair structure and even have a parallel therapeutic effect. Poor staining of strands with very dirty hair is also noted, which is explained by uneven work of sebaceous glandsin which some parts of the head are much fatter than others.

According to experts and experienced hairdressers, the result of dyeing depends on many factors. So, regardless of the purity or salinity of the hair, you must strictly observe painting technique rules, which are detailed in the instructions for its use. This is due to the fact that many manufacturers specifically indicate which hair should be dyed, so neglecting recommendations is highly wrong.

This position is explained by the presence in the composition of modern paints natural oils and plant extracts, neutralizing the effect of aggressive components. Moreover, the modern market offers a huge number of clarifiers on an ammonia-free basis, allowing you to perform the bleaching procedure on a clean head.

Painted curls require constant and competent care, which helps them recover as quickly as possible and acquire a healthy look and unique shine.

• In the process of painting under the influence of ammonia, hair flakes open and cause weakening of the hair. To restore them properly, you need to regularly make herbal baths, apply restorative masks and do not use hot water to wash your hair. It is also forbidden to visit the solarium and to style the hair with the help of stylers, tongs and irons.
• Immediately after staining it is necessary to quickly neutralize the alkali. This can be done using rinsing rinses or stabilizing shampoos.
• Wash your hair should be every 2-3 days. More frequent washing can cause a drying effect and will not allow hair to recover normally.
• Blow dry hair recommended in a natural way. To speed up the process, in some cases it is allowed to use a hair dryer, however, the air in it must be cold.
• Combing colored curls should be carried out using a rounded comb, which has sparse and smooth teeth.
