There is only half a month left before the Spring Festival in 2020. The new year is new, especially the female friends who love beauty. They will choose a perm before the Spring Festival. At the same time, I am worried that there will be serious hair loss after the perm. Today Let’s talk with you about how to choose a perm method that suits you, and how to minimize the harm to your hair.
How does hairstyle affect a person's image?
PERM
PERM development history
Since history, many women who love beauty are looking for a suitable one. My own curly hair was first wrapped around a wooden rod, dried in the sun, and then turned into curls. Later, it was heated in advance with tools such as electric tongs or iron rods, and then the hair was rolled onto the hot rod. Wavy.
This method hurts the hair quality. With the advancement of technology, many ancient methods are gradually eliminated:
Perm
The cold perm of perm Make a new hairstyle. Before and after curling, thiol solution should be used to wet and soften the hair. It contains thioglycolic acid (5%-9%) and pure ammonia (1.3%-1.8%) or monoamine ethanol. Its function is to break the trisulfide cross-links that the hair keratin depends on firmly. Use different rolls to make various shapes. Then it is shaped. This will use an oxidant (such as hydrogen peroxide or perboron hydrochloric acid) to neutralize the acid cold wave, so that it can be shaped and form a lasting wave.
The effect presented by cold wave : The hair that has just been permed is relatively curly when it is wet, and the curl is not very good after it is dried. It must be moisturized, otherwise it will be very frizzy. The hairstyle made by cold perm can maintain a certain degree of durability, and the tips of the hair are relatively elastic, which can make a variety of hairstyles. However, cold perm chemicals are more harmful to hair, and hair is easy to break, change color and fall off.
This method has the characteristics of natural curling, shiny hair, and a small amount of hair loss. It is simpler and safer than electric perm, and is suitable for thin and yellow hair.

Perm the way of perm
Perm is to apply ammonia water to the hair, and then heat, through the heat energy of the current and the chemical and physical effects of the perm potion to make the hair The cell structure is recombined to make a new hairstyle.
The effect presented by hot perm : Just the opposite of cold perm. Hair is not very curly when wet, but the drier the hair becomes more curly, and after a period of time, it will be found to be more natural than just after perm. Compared with cold waves, hot potions often contain more anti-heat agents and hair nutrient supplements. This is because the damage to the hair by heating is more serious, and the damage to the hair is "better". These potions The existence of (such as anti-heat agents) can prevent these injuries to a certain extent. Compared with cold perm, hot perm is more durable and natural, but it is relatively more harmful to hair.
The curl of perm hair can be maintained for a long time, which is more suitable for oily hair. After perm, it can converge and reduce oil. Dry hair is easy to break and discolor.

How to minimize the harm of perm
Regardless of whether it is cold perm or hot perm, the main ingredients of the syrup (softener and setting agent) are basically the same, and the principle is also Basically the same, the disulfide strings (hydrogen bonds and salt bonds) inside the hair are "cut" by softeners, that is, so-called softening, and then the styling agent is used to reorganize the cut disulfide strings. The damage to the hair is also in the same line, so how to minimize the damage to the hair?
Choose the correct perm product
Here mainly refers to the choice of softener and styling agent, Some small barber shops will use some poor hair coloring products in order to reduce costs, so we try to buy well-known brand products when choosing perm products. Regular hair coloring products are generally packaged intact, clearly marked, with formal approval number, hygiene license number, Production batch number, etc. Generally, products of poor quality have a pungent smell, and some may even choke your nose. Try to choose some mild hair dye products.
Pay attention to the frequency of perm
Do not exceed 2-3 times in a year, and do not perform perming and dyeing at the same time. There should be at least one week interval. Because both perm and dye will damage the outermost layer of hair to a certain extent, causing the hair to lose luster, dry and break easily. Continuous perm dyeing can cause hair loss. In addition, long-term use of the hair dryer will damage the hair quality, and the hair will naturally break easily.
Washing hair
Choose the right shampoo
Because most of the perm potions are alkaline, it is easy to destroy the PH environment of the scalp (normal scalp PH environment is Weakly acidic), so it is recommended to use weakly acidic shampoo or add a little white vinegar to the water. You can wash your hair several times a day to keep the scalp clean, which can quickly restore the scalp environment to normal and relieve hair loss.
Finally, perm is not recommended if you can. If you want to change your hairstyle just because of individual appointments or parties, you can try a one-time perm. Use a perm stick and one-time dye to achieve good results. It hurts the hair, but the disadvantage is that the duration is generally no more than one day. The specific choice depends on personal choice.
