Best Hair Straightening Serum: FAQ’s

Does serum make your hair straight?

Serum cannot make your hair straight since serum is neither a treatment for curly hair or a substitute for regular shampoo.
The serum is good since it nourishes your hair thereby making it strong and supple. But using serum alone is not enough to make hair straight. 
First, you must wash your hair with a shampoo that does not contain sulfates or parabens or harsh chemicals. Try doing a scalp massage with a good hair oil that can penetrate deep into the scalp. You can start with a serum and if it’s not enough then you can use oil after that. 
The serum is a lightweight product that already helps in making your hair look smooth, shiny and healthy. So use serum alone for a week, if you don’t get the results, then include hair oil in your regime.

Can we use hair serum daily?

You can use hair serum every time you wash your hair, but it’s best to treat your hair with serum only once or twice a week. 
Serums are usually very rich and can be too heavy for daily use. When you do use a serum, make sure to apply it evenly throughout your hair, from the roots to the tips.

Are hair serums safe?

No, hair serums are not safe, particularly when used regularly. Hair serums are formulated for your hair shaft, not for the roots. Bear in mind that the chemicals in serums can cause damage to your hair if used for prolonged periods. 
They can cause breakage and hair fall. Some hair serums can dry out your hair. Hair serums mainly contain silicone, mineral oils or alcohol. If used for too long, these can strip off the natural oil in your hair and leave it dry, brittle and lifeless.

Can we apply the serum on oiled hair?

plying serum on oiled hair can do more damage than good since serum will not be able to penetrate through the hair shaft because of the oil. However, it is good to apply oil on hair as it helps restore the moisture of the hair and makes it soft. You can apply the serum once you wash your hair to remove the oil.
