Where to find the best hair growth serum

There are multiple environmental factors that can affect the growth of your hair. Stress itself plays a large role in hair loss, but sometimes it is as simple as the products that we use. A head full of long healthy hair can be achievable when eliminating products that strip the hair of natural oils and replacing those with safe products and serums that improve scalp health. The root of your problems begin at the scalp, and hair serums for hair growth work to target impurities that are preventing your hair from growing properly. Aside from conditions within, a good hair serum will rescue the look of brittle and breaking hair. In pursuit of the best hair growth serum, consider which formula is best for your hair type, the brand and the ingredients used to make the product. 

What to know before buying hair growth serum 

Hair Type

Buyers should consider checking to make sure the ingredients in hair growth serums meet their hair type needs. Each hair type will react differently to certain ingredients and formulas. 

  • Oily Hair: Persons with oily hair should look for hair serums that use water-based and nongreasy formulas. A serum that features various oils will weigh down this hair type. Products that work best for people with oily hair will need to be hydrating and not heavy. Oily hair will not require frequent application of hair growth serums.  
  • Dry Hair: Persons with dry hair should look for formulas that contain various natural oils, such as argon, jojoba and almond oils. These oils naturally occur in nature and will hydrate the hair while  providing the shine and moisture that it is lacking. Products that contain biotin and panthenol will work best for this hair type. If your hair is thin, stay away from the excess oil. 
  • Frizzy hair: Persons with naturally frizzy or brittle hair should consider purchasing growth serums with natural oils, just like those with dry hair. This will promote hair strength, while providing necessary hydration that the hair lacks. Natural oils will work to reduce the effects of humidity in the hair and close off the hair cuticle, creating less friction, frizz and static. 


When purchasing a hair growth serum, avoid products that have parabens, sulfates and alcohol. These ingredients will dry out the hair over time and could cause hair loss. Healthy hair is sourced from a healthy scalp. Putting ingredients in your hair that are known to cause scalp irritation could halt hair growth for a period of time. 

  • Parabens: Parabens can disrupt hormones in the body, harm reproductive organs and increase cancer risk. When used abundantly, products that contain parabens can cause scalp irritation. The scalp is very sensitive and should not encounter ingredients that are not gentle. 
  • Sulfates: Sulfates can irritate your eyes, skin, mouth and lungs. Sulfates cause the skin to dry out and can cause irritation in the scalp. If the scalp is too dry, it will cease to produce necessary oils that help the hair grow. 
  • Alcohol: Alcohol can irritate and dry out the hair and scalp and cause split ends over time. This ingredient will leave the hair looking dry and brittle after styling. If you are looking for hair growth serums and find a product that contains drying alcohol, it could end up doing more harm than good. 


When purchasing a hair serum for hair growth, make sure that the brand itself has good reviews.  Make sure the brand sustainably sources its ingredients and pledges not to use harmful products on animals when creating their formula. The brands that care about the animals and the environment also work to make sure their formula is gentle, organic and safe for use on sensitive skin. Just because a brand is not widely known, does not mean that it will not do wonders for the hair. Popularity cannot guarantee the best results. Before purchasing a hair growth serum, consider checking the reviews to see what others who have used the product have said about it. This will give you a clue on the integrity of the brand and its formula for success.  

How much you can expect to spend on hair growth serum

Hair growth serum will cost anywhere from $30-$90, depending on the size of the bottle, the ingredients and the brand. A serum that is widely known and uses the best ingredients to stimulate hair growth quickly will be priced around $50-$90. 

Tips for applying hair growth serum

For best results when applying hair growth serum, first dampen the hair. This will open the hair cuticles and allow the product to absorb more effectively. Then, add one to two drops of hair serum to the palm of your hand and rub it together. Apply this to your hair, working from the ends up to the middle of your hair. If the product is also used for scalp health, apply from tip all the way to the root for the best results. 

Hair growth serum FAQ

What ingredients help my hair grow? 

A. When purchasing a hair growth serum to strengthen and grow your hair, consider looking for ingredients such as peppermint, Jamaican black castor oil and aloe vera. These are just a few of many ingredients that stimulate hair growth and leave the hair feeling stronger and looking healthier. 

Do I need to use hair growth serum every day? 

A. You should not use hair growth serums every time you wash and style your hair. Limit the use of these serums to a couple of times a week. If you have unmanageable and frizzy hair, consider also adding an oil-based product to your hair routine on the days that you are not using the serum.
