How To Repair Keratin Damaged Hair


If you struggle with dry, undefined, and frizzy, and out-of-control hair, then you like the idea of having keratin treatments to help straighten your hair. Additionally, the treatments will provide you with a glossy and healthy appearance on your hair. However, because keratin treatments use high heat to seal your hair, it will cause damage even with a heat protectant on it. When you have hair damage after keratin treatments, you feel that you would have been better off with dry, frizzy, undefined hair. That is because damaged hair is quite brittle and can break easily. The good news is, however, there are methods to repair keratin-damaged hair. Firstly, let’s talk about keratin treatments and what they entail a little more and then go into ways of repair.

Why Can Keratin Treatments Damage Your Hair?

The point of these treatments is to seal the keratin into your hair if it is in bad shape or you want to straighten it because it is too frizzy or curly. Instruments need to heat up to 400 F or just over 204C to lock keratin in the hair. If you use that heat on your hair for short periods, especially if you have a heat protectant, the damage would not be significant. However, keratin treatments can take hours to do.

If your hair isn’t porous, has a history of damage, or is durable to withstand the heat, then keratin damage is not as likely to happen. However, if you have naturally fine hair and colored or bleached your hair often, you will likely endure keratin damage. That is because chances are, before the treatment, your hair was already prone to breakage and brittle. Therefore, all it takes is a lot of exposure to high heat for that to happen. That means the keratin treatment, in that case, would have been the straw that broke the camel’s back.

What if you have healthy and durable hair that you did not treat often, and you began showing signs of damage after the treatment? Sometimes too much keratin can be the culprit too!

Too Much Keratin Would Damage Your Hair In Addition To Formaldehyde

Do you know the saying that too much of a good thing is not so good after all? That applies to keratin too. You need that protein to help fix the situation with your frizzy or dry hair to straighten it out and fortify it. However, if the treatment delivers too much keratin, there is an overload of it which will cause your hair to become brittle.

When there is too much keratin serum applied to your hair, it will cause too much build-up of the protein on hair shafts which will cause them to stiffen, harden, and become sticky. In addition, too much of the protein will create an outer shell, and when that dries up, it will cause friction between hair strands, increasing the chances of it breaking. That is why it is essential to read the instructions on doing the treatments if you are doing it at home. And go to a reputable salon that specializes in these treatments.

Also, in many keratin treatments, there is formaldehyde which is a potent chemical that is in embalming fluid. It helps rearrange hair bonds, but too much of the chemical can cause breakage because of oxidative stress. So now, let’s talk about how to repair keratin-damaged hair.

Massage Olive Oil In Your Hair

You can always massage olive oil into your hair, and you will want to start rubbing it in the scalp and go down to the ends with your fingertips. Then take a comb and comb it through your hair strands so the olive oil covers them. You can leave the olive oil in as long as you’d like, and you may even leave it in overnight if you choose to do so. Afterward, shampoo and condition your hair well. The olive oil will moisturize and repair damaged hair regardless of the cause of damage. You can do this several times a week if the damage is significant. You can also use almond oil, but the method is different.

Repair Your Hair With Almond Oil

Almond oil contains many essential nutrients, including Vitamins A and E, and even though people use it for skincare, you can use it to repair keratin-damaged hair. The way to treat your hair with almond oil is to warm the oil in a pot on low heat slightly. After finishing, you will want to dampen your hair and then apply the oil to it. First, ensure you get the oil on all strands, and then cover your hair for a half-hour with a towel. After the half-hour is up, then you will want to rinse. However, if you have an allergy to almonds, you will not want to use this oil. You can always use olive or coconut oil.

Repair Hair With Coconut Oil

There is a reason that so many people love coconut oil, and it is because it has so many nutrients and healing properties. In addition, it helps heal damaged hair quite well. You will want to apply the coconut oil all through your hair and massage it, and leave it in for at least a half-hour. However, there is something to keep in mind with this treatment. If you want to utilize this treatment for treating keratin-damaged hair, find a day when you can stay home because removing coconut oil from your hair is an exhausting undertaking. If you don’t like these treatment ideas, there is another simple hack you can utilize. Let’s go over that now.

Cut Your Split Ends And Keep Your Hair Moistened

If you don’t relish the idea of dousing your hair with oil to treat keratin-damaged hair, then you can do a simple thing instead. The sign of keratin-damaged hair has split ends, so you will want to have those cut. Additionally, keep a humidifier in your room and have it running when you are sleeping each night. It will help keep your hair moist, which will eventually heal the damage from the keratin treatment. That method will take longer to heal your hair than the oils to treat it, but it is much less messy and more convenient. That right there makes this method appealing.


When you go for keratin treatments, the idea is to straighten your frizzy or unruly hair and give it a healthy glow. However, the high heat that comes with these treatments can damage your hair. In addition, sometimes, you may add too much keratin to your hair, which can also cause damage, and use formaldehyde. However, there are ways to repair your keratin-damaged hair. For example, you can use olive oil, coconut oil, or almond oil to heal your hair. However, those are messy, and you may prefer to cut off your split ends and keep your hair moist by running a humidifier in your room each night!
