Keratin treatment is a process that infuses your hair with proteins to make it feel softer and smoother. It fuses hair bonds together with the treatment using heat, either through blow-drying, steam, or flat iron. If done in a salon, the results could last up to a couple of months but if it is done with a home keratin treatment, the result can last for a couple of weeks only.
The good thing is, there are a variety of hair products that incorporate keratin into their formula for easy maintenance at home. With regular use, your hair will be revitalized in no time and it will lessen your use of styling tools. It will also keep your hair healthy inside and out!
Keratin is a major protein of human hair, and it is important in maintaining its tensile strength. Chemical treatment of hair (e.g., bleaching) may damage keratin leading to a decrease in strength of the hair. It's important, however, to be familiar with the different options out there. Remember, not all keratin treatments are created equal.
A study by Basit, A. et al. found that the application of keratin, particularly, K31 allows it to fill in the gaps of damaged hair, leading to a significant increase in hair diameter, tensile strength, and surface smoothness.
You can achieve silky smooth hair right in the comfort of your own home. Nowadays, keratin is infused in different hair products, ranging from your everyday conditioner to the more intensive hair masks. It depends on which one suits your preference.
Although keep in mind that at-home treatments would not have exactly the same effect as a salon treatment would. They would not last as long and are considered temporary fixes which would need constant maintenance in order to achieve your desired effect.
Hair masks have more moisture content and are comprised of nourishing oils and strengtheners that soften, moisturizes, and regenerates hair. It functions by penetrating deep into your hair follicles and nourishes it from the inside that is why it is applied from root to tip.
Masks take a bit of time for it to take effect, around 20 minutes to an hour to allow it to deeply condition and nourish your hair. Sometimes masks need a bit of heat to activate the product.
Due to the potency of its moisturizing effects, while great at repairing damage, is not ideal for everyday use as it could weigh down your hair and make it oily. Ideally, masks are meant to be used once or twice a week, it can be applied on dry hair before you shampoo it for intense repair.
Masks for the hair help restore moisture and softness. A journal published by Gavazzoni Dias on hair cosmetics identified the need for moisturizing hair and one option is through hair masks preferably containing hydrolyzed amino acids, silicones, and vegetable oils to remove the residues on the hair without stripping the fiber.
Another study by Helen, I. et al. explored the effect of vegetable proteins in a hair mask and the experimental results showed increased hair smoothness, hair strength, and morphology of damaged hair.
Conditioners function to smooth your hair and tame frizz however, it can only make hair silky and smooth temporarily. Its effects are not as lasting as hair masks as it is applied on your hair and not your scalp. All sorts of hair types can utilize the right conditioner.
Its effects can be seen almost immediately, after about 2-5 minutes. It is ideal for everyday use as it is specifically designed that way that is why it is more lightweight compared to masks. Unlike masks, conditioners must be applied after shampooing to remove oil, and dirt as it is a post-wash type of treatment.
Sprays are ideal if you don’t have a lot of time for treatment and deep conditioning your hair, as it does not take up too much time. It can condition and protect your hair from damage and styling tools by acting as a barrier, strengthening it, and at the same time making it smoother and softer instantly.
Simply mist the keratin spray to your hair before going about your hair routine such as blow drying or ironing for an instant fix, as this will activate the product leaving you with more manageable hair without much effort.
At the end of the day, it's important that you research what you're putting onto your hair as some products may be labeled as keratin-infused with a hefty price tag but are really just overpriced conditioners.
Also, it would be good to take extra care with sprays as the contents can be sprayed onto not just your hair but your face or other parts of your body. You wouldn't want to develop a reaction to these products in other exposed areas.
Like conditioners, leave-in treatments can soften and tame hair to make styling easier. It provides the ideal nourishment to your hair especially if you lack the time making it softer, and strengthening it at the same time.
It acts as a barrier to protect hair against heat and protects it from damage from the environment and your styling tools. Moisturizes and smooths frizzy, and tangled hair, taming it. Apply it while your hair is still damp, and comb through your hair to make sure it is distributed evenly.
Leave-in keratin treatments provide nourishment by filling in the gaps of damaged hair, leading to a significant increase in hair diameter, tensile strength, and surface smoothness.
Protein hydrolysates, in particular, those with low molecular weight, have been shown to protect hair against chemical and environmental damage. Look for keratin hydrolysates - these are efficient restorers in hair care processes.
When buying keratin treatments, try to choose products that have natural moisturizers such as olive oil, argan, coconut oil, shea butter, and sunflower oil. This will aid the keratin and give you optimum results while nourishing your hair.
Olive oil is great for moisturizing your scalp and reducing irritation, making your scalp healthier. Argan oil is another excellent moisturizer and contains a lot of antioxidants and helps fight dandruff. It is also responsible for making your hair shiny and reducing frizz. Coconut oil is ideal for reducing oil buildup in your hair, as well as reducing hair breakage by strengthening and nourishing it.
Shea butter softens your hair and contains a lot of vitamin A and E, which has healing properties as well as reduces frizz. Lastly, sunflower oil contains antioxidants and vitamin E to soothe hair, and lock in moisture. It is ideal for dull and dry hair, as it moisturizes and reduces frizz, and stimulates healthy hair growth.
Studies have shown that applying hair oil is important in protecting the hair from damage. Some oils penetrate the hair and reduce the amount of water absorbed in the hair, leading to less swelling. This can reduce the cycle of repeated swelling and drying, a factor that can damage hair.
Hair oils can fill the gap between the cuticle cells and prevent the penetration of aggressive substances such as surfactants into the follicle. Also, applying oil on a regular basis can enhance lubrication of the shaft and help prevent hair breakage.
Formaldehyde is a colorless, odorless, and strong smelling gas commonly used in furniture, countertops, even nail polish. It is found in keratin treatments to help lock in straightened hair. However, it raises concerns as it is considered a carcinogen. It can also cause irritation to your eyes and nose.
It was discovered, however, that formaldehyde is a carcinogen and the maximum safe concentration of formaldehyde set by the US Cosmetic Ingredient Review Expert Panel is less than 0.2%. Unacceptably high concentrations of formaldehyde have been reported in some keratin treatments. So definitely, choosing a formaldehyde-free product is a must!
A word of caution! Keep an eye out for products listed as formaldehyde-free but actually contain ingredients such as formalin, formic aldehyde, methanol, methylene glycol, methylene oxide, that break down into formaldehyde during the heat application stage. Tricky!
