Best Hair Straightening Serum: FAQs

What serum is good for frizzy hair before straightening?

The best hair straightening serum for frizzy hair before striaghtening is the L’Oreal Paris Advanced Hairstyle Blow Dry It Thermal Smoother Cream. This serum is designed to protect hair from heat damage while also providing long-lasting frizz control.

It contains a lightweight formula that won’t weigh hair down or leave it feeling greasy, making it a great option for those with fine or thin hair.

Additionally, it can help to smooth out hair and make it easier to straighten. It is recommended to apply this serum on towel-dried hair before blow-drying and straightening for the best results.

Does serum make your hair straight?

No, serum alone does not make your hair straight. Hair serums are used primarily to add shine, reduce frizz, and protect hair from heat damage. While some serums may have slight smoothing effects, they are not designed to alter the natural texture of your hair.

If you want straight hair, you will need to use heat styling tools like a straightening iron or have a chemical treatment like a Japanese hair straightening or keratin treatment.

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.
