Keratin treatment is mainly a chemical process. They are namely making your hair straight in addition to being smooth and shiny.

However, since this treatment contains many chemicals, it is not a completely harmless treatment for hair.

Some Factors to Know About Keratin Treatment
If you want shiny, sleek, frizz-free hair, plenty of hair treatments are available. Is keratin treatment any better than those other treatments?
Why should you choose keratin treatment over others? Let’s find out what you are getting from keratin treatment.
1. Keratin for Strengthening
Our hair is made of keratin. Traditional hair styling using a heat tool can damage the link with that keratin. Breakage and split ends are common problems when you lack keratin. Hence, this treatment provides your hair with the lost keratin in your follicle, making it stronger and healthier.
2. Prevents Frizz
Frizz occurs when hair lacks moisture. When dry hair gets in touch with humidity, it attacks the hair making it frizzy. The hair dries out when it gets damaged, and the hair cells open up due to breakage. Keratin helps fill up those gaps and tame the frizz. It also makes the hair smooth and silky.
3. Damage Repair
As we discussed before, keratin fills up the pores. As a result, hair becomes smooth. Keratin also adds an extra layer of protein to the hair, one of the critical elements of silky and shiny hair. Keratin shampoo, conditioner, and oil help to prevent breakage and split ends. All in all, this treatment repairs damaged hair.
4. Switching Products
You must change your hair products after using a keratin treatment. Giving up your old hair products and switching to new ones is necessary when you’ve done keratin treatment.

Normally, hair treatments contain formaldehyde, which is toxic. If your stylist uses something that is formaldehyde-free, it will probably turn into formaldehyde when mixed with water or put into heat. But now there are also some alternatives.

Permanent straightening, also called Japanese hair straightening, use thermal reconditioning ingredients to straighten any hair type permanently. 
This straightening procedure uses high-heat products, chemicals, and flat iron. Namely, this procedure breaks your hair bonds, reforms the fiber, and makes your hair straighten permanently. Nevertheless, you may need a touch-up every year.
This process generally takes about 4 -5 hours to complete depending on the length of your hair. During the procedure, the molecular bonds of your strands become softened and reformed into a straight pattern.
Thus, after successfully finishing the straightening, you will get smooth, silky, and incredibly straight hair.
However, permanent straightening can make your hair vulnerable to future damage and make it brittle.
Therefore, you always need to take care of your hair. Furthermore, it will make your hair super dry, so most hair experts do not recommend applying this straightening method on bleached, colored, or highlighted hair.
Is It Really Permanent?
The method is called permanent straightening, which is valid at some points. But it will not last forever. Your hair will remain straight until new hair grows.
Namely, the newly grown hair will be frizzy or curly. But the straighter hair (the hairs which were permanently straightened) will remain straight. You do not need to worry if your hair growth rate is meager.
Some Factors to Know About Permanent Straightening
1. Types of Japanese Treatment
There are many types of permanent straightening, and the most popular type is Japanese straightening. With this straightening method, your curls can vanish forever, and you will get longer-lasting smooth, silky, and straight hair than any other straightening treatment. However, this treatment is more expensive than others.
2. Types of Hair
You must consider your hair type before applying Permanent or Japanese Straightening Treatments on your hair. This hair straightening procedure does not work if you have thin or weak strands.
3. This is Not a Home Treatment
Going to a salon is necessary if you want this treatment. A non-professional hand can burn your hair.
4. Last Longer Than Any Treatment
This treatment lasts longer than any other available treatment. So, this is the obvious treatment choice if you need to straighten your hair almost permanently.
5. The Damages
After this treatment, your hair becomes vulnerable. So, there will be more risk of getting frizzy, dry, and broken hair. Thus, you should avoid this treatment if you cannot afford to constantly take care of your hair and spend some money on more expensive products.
Pros & Cons of Permanent Straightening

|2. Your hair will become silky, glossy, and straight.
|2. Need a saloon or experienced hairstylist.
|3. You rarely need blow-drying after taking this treatment.
|3. Makes your hair dry, frizzy, and vulnerable to future damage

|4. Can affect the texture of newly grown strands.
So, which one will you choose? Permanent straightening makes your hair straighten better than any other treatment.
It does not work like flat irons, which make your hair dry and do not give it a naturally straight look.
This type of treatment is best for very thick and curly hair. Once your hair grows again, the hair’s roots will become curly, but the ends will be straightened.
If you do not like the prospect of regrowing hair and are aware of the possibility of making your hair dry, frizzy, or damaged, then you can go for keratin treatments.
This treatment also requires less time and maintenance. Additionally, you can do this keratin straightening process at home. And it costs less than the permanent straightening treatment. Ultimately, the choice is yours.
