Best Serum for Hair Growth and Thickness in India - How to Choose The Right Hair Serum?


Weather conditions in India are unpredictable! And so is our hair. No matter how regular we are with oiling, shampooing, and even conditioning, sometimes our hair just ends up getting dull, frizzy, damaged, and even tangled. 

It is advisable to focus on products with potent chemicals that are well-known for their advantages when selecting the best hair serum for growth and thickness. Always look for serums that contain keratin, biotin, and natural oils that are known to strengthen and nourish hair, such as argan or jojoba. Furthermore, choose serums that are dermatologist-recommended and free of dangerous ingredients.

Serums come in different varieties to address different hair issues. While moisturizing serums hydrate and repair damaged strands, growth and thickening serums promote hair growth and thickness. For example, peptide serums increase hair thickness, biotin serums fortify hair strands, and caffeine serums increase blood flow to the scalp to encourage growth. Aloe vera serums soothe the scalp, keratin serums repair damage, and vitamin C serums increase the formation of collagen.

Even if you’re someone who likes to keep their hair care regime to a minimum, Having the perfect serum can add so much more to your hair nourishment. Let’s understand how serums work for different hair types and the best serums that you can go for!

What are Hair Serums?

Hair serum is a concentrated formula designed to moisturize, detangle, and smooth your hair texture. It is a liquid-based solution that addresses issues like frizziness, lack of thickness, and dullness.

If you have days when even a good hair wash doesn’t seem to work, serum is the formula that can come to your rescue!

Originally, hair serums were made with ingredients such as sulfate, silicones, parabens, GMOs, mineral oils, and other potentially harmful chemicals. While these ingredients might have initially resulted in soft and lustrous hair, they often had disadvantages over the long term if used continuously.

Nowadays, products with tested solutions and a natural base may take some time to show results, but consistent use can make the results last longer, especially without any side effects.


Types of Hair Serum

There are various types of serums that can be used specifically for your particular problem, Here is a list of them: 

  1. Growth and Thickening Serums: Focuses on promoting hair growth and increasing thickness
  1. Frizz Control and Smoothing Serums: Focuses on controlling Frizz, smoothening hair texture, and adding shine.
  1. Hydrating and Moisturizing Serums: Focuses on Moisturizing and hydrating hair for people having brittle hair texture

Best Hair Serum for Hair Growth 

There are many hair serums out there but how to know which suits us best? Here is a list of carefully picked hair serums that will definitely help in hair growth and thickness. 

1. Biotin Serum

Serums containing biotin are well known for strengthening hair strands and encouraging growth. The synthesis of keratin, a crucial protein in hair, is aided by biotin, sometimes referred to as vitamin B7. 

This process reduces hair loss and increases hair thickness. Frequent application of biotin serums can also increase the flexibility of hair, reducing its vulnerability to breakage and damage.

2. Peptide Serum

Amino acid chains found in peptide serums aid in thickening and promoting hair growth. Peptides help keep hair follicles healthy, promote new hair growth, and fortify existing hair, giving you longer, fuller hair. 

It increases hair's strength, flexibility, and resistance to damage, peptides can also enhance the appearance and general health of hair.


3. Caffeine Serum

Coffee serums increase blood flow to the scalp, which promotes hair growth. Hair follicles are nourished by the increased blood flow, which promotes hair growth and lessens hair loss. 

Additionally, caffeine adds luster and strengthens the roots of hair. Caffeine also contains anti-inflammatory qualities that help relieve irritated scalps and provide a more favorable environment for the scalp.


4. Vitamin C Serum

Collagen is produced more readily by vitamin C serums, strengthening and encouraging hair growth. They also shield hair from environmental stresses and free radical damage. Vitamin C serums can improve hair radiance and shine when used on a regular basis. In addition to preventing hair loss, vitamin C keeps the scalp healthy by lessening flakiness and dryness.


5. Keratin Serum

Keratin serums are intended to strengthen and restore hair by restoring the natural protein found in hair that has been lost. These serums leave hair looking healthier and more resilient by strengthening, smoothing, and preventing breakage. 

They also help to minimize frizz. Additionally, keratin serums can aid in the restoration of damage brought on by chemical treatments, heat styling, and environmental stresses.


6. Aloe Vera Serum

Aloe Vera serums are a great way to hydrate the scalp, soothe it, and minimize irritation. Aloe vera's natural enzymes and vitamins condition hair, lessen dandruff, and encourage healthy hair development, leaving it manageable and soft. The antibacterial and antifungal qualities of aloe vera can also support healthy scalp maintenance and help stave off problems like dandruff and scalp infections.


7. Niacinamide Serum

Hair follicles and the scalp are healthier when niacinamide serums are used. They improve the function of the scalp's barrier, lessen inflammation, and retain more moisture. 

Stronger, healthier hair and less hair loss are the outcomes you can truly expect from adding Niacinamide. Additionally, niacinamide balances oil production, so it's good for both dry and oily scalp types. It can also make hair look and feel better overall.


8. Ginseng Serum

Ginseng serums strengthen hair follicles and increase blood flow to the scalp, which promotes hair growth. Ginseng's antioxidant qualities shield hair from harm and encourage fuller, healthier hair. 

Additionally, ginseng contains anti-inflammatory properties that help calm the scalp and lessen dandruff, which promotes a healthy scalp and healthier hair development.


9. Hyaluronic Acid Serum

Serums containing hyaluronic acid give the scalp and hair a powerful dose of moisture. They lessen breakage, keep moisture in, and stop drying out.

These serums work wonders for encouraging hair development and preserving a healthy scalp environment. Additionally, hyaluronic acid can give hair body and volume, giving it a fuller, more vibrant appearance.


10. Jojoba Oil Serum

Vitamins and minerals abundant in jojoba oil serums nurture the hair and scalp. Softer, more lustrous, and healthier hair is the consequence of their assistance in balancing oil production, reducing dandruff, and adding moisture. 

Jojoba oil is a great moisturizer that doesn't weigh down or leave hair feeling greasy because it is comparable to the natural oils produced by the scalp.


11. Green Tea Extract Serum

Antioxidants found in green tea extract serums shield hair from harm and encourage development. Stronger, healthier hair is the consequence of their assistance in reducing hair loss, stimulating hair follicles, and enhancing scalp health. 

Green tea's anti-inflammatory qualities can also improve the quality of your hair by soothing an irritated scalp and lowering dandruff.


12. Amla (Indian Gooseberry) Serum

Vitamin C and other nutrients found in amla serums strengthen hair roots, encourage growth, and lessen hair loss. They also make hair seem healthier and more vibrant by enhancing its natural color and luster. 

Amla is a complete solution for keeping hair healthy, strong, and lustrous because of its antioxidant qualities, which shield hair from the elements and can help delay the onset of gray hair.

Myths & Facts about Hair Serums

Here are some myths related to hair serums and the actual facts about them. Let’s go through each and understand the difference in the previous assumptions and the reality behind hair serums.


Myth: Hair serums cause greasy hair.

Fact: Hair serums are designed to provide hair with a light touch of hydration and smoothness without making it oily or greasy. In order to increase shine and manageability, they usually contain silicones or other conditioning ingredients that coat the hair shaft.


Myth: Hair serums can contribute to oiliness.

Fact: Hair serums are intended to be applied sparingly to the ends or lengths of hair, staying away from the scalp. Serums should not lead to excessive oiliness when used properly. If you're worried about oiliness, look for lightweight or non-comedogenic formulas.


Myth: Split ends can be fixed with hair serums.

Fact: Split ends can be momentarily smoothed and sealed using hair serums, but they cannot be permanently repaired. Split ends must be removed and healthy hair must be maintained with routine trims.


Myth: Using hair serums, thin hair will appear thicker.

Fact: Certain compounds in hair serums can temporarily thicken the hair shaft, giving the appearance of thicker hair. This impact, however, varies based on the formulation and kind of hair and is not always permanent.


Myth: Using hair serums can make you lose hair.

Fact: Hair serums do not promote hair loss when taken as prescribed. In actuality, serums that enhance circulation and scalp health can aid in the development of healthy hair. Steer clear of utilizing serums excessively or applying them directly to the scalp.
