The hair smoothening craze doesn’t look like it is going to die down anytime soon. So in this post, I going to explain all about hair smoothening from how it is being done, the different varieties of hair smoothening aka relaxing its pros, cons to the cost and longevity of the treatment. If you are on the fence whether or not to do hair smoothing then this post will definitely be useful to help you with the decision. Hair Smoothening has various names such as Rebonding, Keratin Treatment, Brazilian Blowout, Cysteine Treatment, etc. If you want straight, sleek, shiny, frizz-free hair without using flat irons or blow dryers daily these are the best bet.

Hair Smoothening Before & After

Hair Smoothening Procedure-

Firstly, a straightener cream is applied from scalp to the tip of the hair and covered with aluminum foils. That cream is left to seep into the hair strands for several hours. This cream changes the pattern of your hair strand from curly/wavy to straight sleek hair. After leaving it for a couple of hours it is then rinsed off with water and small sections of hair are taken and flat ironed carefully for perfectly straight hair. Secondly, a neutralizer cream is applied and left for another hour or so to permanently seal the straightened effect in the hair. After rinsing the second cream a blow dry with cool setting will be given to the new hair. The effects of this treatment will stay this way for about 6-9 months.

Safety Measures During The Hair Smoothening-

These hair smoothening creams contain formaldehyde which is highly toxic and can cause scalp irritation, rashes, eye irritation from the fumes. Make sure you go to a well-reputed place for the treatment which has a good ventilation system. It’s best to avoid this procedure if you already have Scalp & Skin problems like Dandruff, Hair-fall, Psoriasis, Seborrheic Eczema, Acne, etc, as the chemicals can aggravate it even more. Or go for a milder treatment which doesn’t contain any formaldehyde. Like Cysteine Hair Treatments which does not contain any Formaldehyde and is a milder safer alternative.


After the hair smoothening it is very important to buy a good shampoo, conditioner and hair mask to protect your new hairdo. Good hair care products can make or break your hair so do a lot of research before buying something. Dry hair becomes even drier. Hair fall cannot be controlled whatsoever. Hair strands start to break horribly. So take those weekly oil massages and hair masks (DIY Masks or Buy it from stores) and most importantly a good diet can change the way your hair & skin looks.

        You can opt for Keratin treatment to tame the frizz and to smooth the cuticles and shaft! Make sure it’s formaldehyde free. Also for oily scalp humidity plays a big role.

        Try deep conditioning and nourishing hair masks. You can buy them from salons or DIY few masks at home. Make sure you do it frequently to see results.
