It is very important to select a hair-thickening serum with the right ingredients to get the best results. You should select hair growth serums according to your hair type and hair needs. Using the wrong product can cause long-term damage to your hair health. Given below are some factors to consider while choosing the best hair thickening serums.
How To Select The Right Hair Thickening Serum For Your Hair Type
- Ingredients
Always prefer natural ingredients such as coconut oil and aloe vera over harsh chemicals. The good ingredients to look for in hair-thickening serums are vitamin E, keratin, caffeine, argan oil, green tea extracts, DTH blockers, raspberry ketone, ginger, and ginseng extracts. You should avoid the ingredients that you are allergic to. Also, avoid using hair serums that include sulfate, paraben, gluten, artificial fragrances and colors, ammonia, and other harmful chemicals.
- Formula
There are two types of hair growth serums, oil and foam. A topical oil may make thin or fine hair appear greasy, but foam offers a lighter, mousse-like solution that is easier to absorb into your hair. Dry hair needs more moisturizering therefore, oil-based hair serums are recommended for dry hair. While some topical treatments must be used once or twice a day, others can be used occasionally or only on wash days. Look out for hair serums that suit your lifestyle and hair care regimen.
- Price
Pick a serum according to your budget. Look for products from both high-end and drugstore brands. You can also select the best hair-thickening serum based on other users’ experiences but look out for the factors that work for you.
