Glycolic Acid and Bleached Hair
On the Effect of Glycolic Acid on Hair Bleaching
There is a way to beauty hair in the world, and those who bleach want a different color. However, after hair bleaching, the hair is damaged, and everyone is looking for ways to nourish it. Glycolic acid has a special impact on hair bleaching.

The relationship between glycolic acid and hair bleaching is primarily due to its chemical properties. Glycolic acid has a unique molecular structure that can interact with the chemical structure of hair damaged after bleaching. During hair bleaching, the chemicals in the hair dye break the chromogen structure of the hair, making the hair lighter, and then also damage the outer scales of the hair, causing the internal protein structure to be exposed. Glycolic acid can penetrate into the inside of the hair, bind to exposed proteins, or reshape some damaged structures, or affect the chemical bonds between proteins, which is the basis for the effect of glycolic acid on hair bleaching.

Looking at its action process, the concentration of glycolic acid is the main factor. Low concentration glycolic acid can gently clean the hair after bleaching, remove dirt and residual hair dye, and cause little damage to the hair. Because of its mild acidity, it can adjust the pH of the surface of the hair, return the hair to a balanced state, and increase the luster and flexibility. However, if the concentration is too high, although the cleaning power is strong, it may over-corrode the hair scales, exacerbate the loss of protein, and make the hair dry and easy to break. There are examples as evidence. After a certain nail is bleached, it is treated with high-concentration glycolic acid. At first, the hair feels clean, but soon the hair is like dead grass, making it difficult to comb.

Furthermore, the action time cannot be ignored. Short-term exposure to glycolic acid, or only to the surface of the hair, cleans and repairs slightly. If the contact time is long, the glycolic acid penetrates too much into the hair, or excessively changes the protein structure, affecting the normal physical properties of the hair. If a certain ethyl uses glycolic acid for hair care, the effect varies depending on the duration. If it is used for a short time, the hair will be smooth; if it is used for a long time, the hair quality will deteriorate.

The frequency of use of glycolic acid is also important. Moderate use can regularly repair hair bleaching damage and keep However, if it is used frequently, even if the concentration is appropriate, it may accumulate very little damage, which will eventually cause the hair to be overwhelmed.

To sum up, glycolic acid is like a double-edged sword for hair bleaching. When used properly, it can protect the hair and increase its beauty; if used inappropriately, it will damage the hair and damage its original. Hairdressers should know the characteristics of glycolic acid in detail, and use it reasonably according to the actual situation of the hair bleaching, so that the hair can be nourished and kept youthful.
