Yes, hair serum can have side effects such as scalp irritation and dryness if used in excess.
But when used correctly, it can do wonders for your hair. The primary purpose of a serum is to provide shine and smoothness to the hair strands. It does this by creating a protective barrier around each individual strand which helps repel humidity, reduce frizziness, and prevent damage from heat styling tools such as flat irons or curling wands.
Serums are also great for providing nourishment to damaged hair as many products contain ingredients that help restore moisture levels and strengthen the follicles from within. A good quality serum can add luster and body to dull locks while taming flyaways at the same time. If you have curly or wavy hair, applying a small amount of serum before blow-drying will give definition and control without leaving your mane looking greasy or weighed down with product build up. For those who colour their hair regularly, using an appropriate serum formulated specifically for coloured tresses will protect against fading whilst adding vibrancy back into your shade between salon visits.
When shopping for serums be sure to read labels carefully so you know exactly whats in them – look out for natural oils like argan oil or jojoba oil which not only condition but also promote healthy growth; vitamins such as B5 which strengthens roots; proteins that repair split ends; moisturizers such as glycerin that hydrates dry strands; silicones like dimethicone which seals in hydration; UV filters that fight off damaging rays from the sun and other environmental factors; all these combined together are the key components of most serums on todays market making them an essential part of any haircare routine!
