There is a huge variety of hair growth serums, with each one meticulously created and prepared to cater to every type of hair, giving your strands the nourishment they require. Learn everything there is to know about the best hair growth serum for men and women, to get noticeably fuller, thicker hair in a matter of weeks. Read on!

What is a Hair Growth Serum?

A hair growth serum is different from regular hair serums. Hair serums help improve the appearance of hair by smoothing it and making it look lustrous. It may also protect the hair from environmental damage. A hair serum helps detangle your hair and makes the hair styling process more manageable.

On the other hand, a hair serum for hair growth is formulated with active ingredients that go deep into your scalp to nourish hair follicles and support hair growth.

When to Apply a Hair Growth Serum?

A hair serum is a completely leave-in product that you can apply after a hair wash and go on about the day. Using it will reduce frizziness and keep your hair feeling silky and shiny.

A hair growth serum needs to be applied at different times of the day based on the ingredient type. For example, some contain stress-busting ingredients, such as melatonin, that are best effective for use before sleep.

But generally, hair growth serums can be applied to a clean scalp at any time of the day. They need to be kept on for a long time for the ingredients to get absorbed. No washing is required.

Active Ingredients To Look for

When choosing the best hair growth serum for women or men, it is important to scan the label to pick ingredients that address your hair concerns. The following list of active ingredients will help you buy the best hair growth serum:

  • Minoxidil: Minoxidil is a beneficial ingredient for your hair follicles. It widens the hair follicles and increases the amount of oxygen, blood, and nutrients that can get to them. Using a hair growth serum infused with minoxidil promotes hair development and thickens and strengthens your current hair. It’s been tried and tested in numerous hair growth products with positive results.
  • Caffeine: Caffeine is the same stimulant in your coffee that helps you wake up in the morning. It can also stimulate the follicles in your hair. When applied topically, caffeine increases blood circulation to the scalp, providing your hair roots with extra nutrition. Using it helps counter the effects of DHT (a male hormone that can shrink hair follicles) and prevents hair loss.
  • Redensyl: Redensyl is the ultimate hair follicle superhero. It targets stem cells, which are the building blocks that help develop new hair in your hair follicles. Massaging a hair growth serum formulated with redensyl helps regenerate hair and gradually makes it thicker and denser.
  • Anagain: Anagain is a wonder product for thin hair that is made from organic pea sprouts. It supports the hair growth cycle and provides stronger and longer hair. Additionally, it increases your hair’s general density, giving it a fuller, healthier look. If you experience slow hair growth, you can opt for hair growth serums with this ingredient.
  • Cressatine: It is an active ingredient in hair care products that helps prolong hair growth and strengthens hair strands. It also improves keratin production in hair, which is a vital protein that makes up your hair. So, if your hair getting thinner, you can look for this ingredient.
  • Procapil: Procapil blocks DHT’s actions; DHT is a male hormone that can lead to hair loss. It also unclogs the hair follicles, as proper nourishment of the hair serum can reach right into the roots. This promotes thicker, healthier hair development and helps stop hair loss before it starts.
  • Capilla Longa: Capilla longa is made from turmeric; a powerful herb that acts as a calming balm for the scalp. It increases the flow of blood to your hair follicles and induces better hair growth. Additionally, it shields your hair from oxidative damage and maintains its strength and vibrancy. If you want to manage dull and dry hair, this ingredient could be what you need.


Hair growth serums are enriched with active ingredients that promote healthy hair growth. To get the maximum benefits from using hair serums for hair growth, you need to look for a set of active ingredients that address your hair concerns. Some of these active ingredients include caffeine, cressatine, minoxidil, etc. You also need to apply them properly to the scalp and let the serum be absorbed there.
