For instance, frizzy and splitting hair would need the help of frizz-control hair serum. The same can be said for other hair types and issues.

Nourishing ingredients

Hair serums contain one form of silicone or the other. The silicone coats your hair, trapping nutrients in and out. As a result, you need nutritional and beneficial ingredients in your serum.

They need to be nourishing at the same time when you use them. The serums need hydrating and moisturizing ingredients like glycerin, green tea extract, vitamin E, and others.

You also need light oils that would not weigh your hair down. Oils like jojoba oil, argan oil, coconut oil, or castor oil are natural oils that help in moisturizing and shining your hair strands.

Serum texture

The oils have to be lightweight to slip easily through your hair strands. Furthermore, the oils make it easier to apply the serums daily. If the serums contain lightweight oils or formulas, the serum can be used every day.

However, thick serums do not fit daily use to improve your hair. You can use it once or twice a week. Thick serums can also build up in your hair. Consequently, it is advised you stay away from heavy hair serums.
