Instead, it enhances the curliness and smoothness of the hair (1). Also, it smooths frizz, adds shine, and protects your hair from environmental aggressors.

Now, let’s answer the question that is probably on your mind.

How Do You Know Whether You Should Use A Serum?

If you are using styling tools like curling or flat irons regularly, or if you feel that your hair is missing that bounce, then give it some extra moisture and nourishment in the form of hair serum. Your hair may look dull and brittle when it loses all the moisture. Also, it needs a bit of revitalization if you are constantly playing a tug of war with your hairbrush.

Most people use a hair serum to prevent dry and damaged hair. Some start using it once their hair turns dull or tangled, while others might use it to protect it from the heat from hair styling tools. The following steps should help you pick and use the right hair serum.

How To Use A Hair Serum?

1. Find The Perfect Product For Your Hair Type

• Like any other grooming product, every brand of hair serum uses different ingredients that may benefit certain hair types and do very little for others.
• You must find the perfect product best suited for your hair type. You must also be aware of the ingredients used. This could often mean experimenting with a few products before finding the right one. Also, there is a misconception that people with fine hair cannot use any serums because serums will make their hair flat. But, in reality, those with fine hair also can use serums with lighter formulas.
• If you are one who styles their hair often, then you should opt for the products that also act against the heat damage from styling tools like curling or flat irons and blow dryers
• Always choose hair serums with keratin as an ingredient if your hair is already damaged. It can help put protein back in the hair.
• Hair serums can also be used as quick touch-ups on your hair any time throughout the day if your mane is looking dull and dry.

2. Wash Your Hair Thoroughly Before Application

• One must remember that hair serum is only applied to shampooed hair. Unlike hair mousse or hair sprays, hair serum is primarily a source of nourishment for your hair, even though it does help to style and detangle it as well. The primary purpose of hair serum is to protect your hair against dust and grime. Hence, applying it on unwashed hair will defeat the purpose.
• Often, popular brands manufacture a complete range of hair grooming products that include shampoo, conditioner, and hair serum that are made to complement each other. Applying hair serum before washing your hair is the optional step. Some people find that it can help reduce frizz and dryness.
• If you are trying out a hair serum for the first time, use one that comes with a compatible shampoo and conditioner in the same hair care range. Shampoo your hair thoroughly, follow it up with a conditioner, and finally apply the hair serum.

3. How To Apply Serum To Your Hair

• Depending on the length and density of your hair, take two to six drops of the hair serum and rub it between your palms.
• Hair serum is best applied on just-washed hair, so make sure your hair is towel-dried or slightly damp.
• Flip your hair forwards and start applying the serum on the hair that falls over your face, going upwards from the tips of your hair. Massage the tips, as the hair serum works well on split ends. Flip the hair back again, take two to four more drops of the serum, and massage it well, starting at the back and moving forward to the front of the hair.
• Once done, you can take a few more drops and apply the serum all over your hair for efficient application.
• Hair serums work best on damp hair. If you want to apply hair serum on your damp hair, then remember that blow-drying your hair is absolutely essential.

4. Post-Application Hair Care

• Once you have applied the serum effectively to your hair, brush it downwards. This will help you easily detangle your hair.
• After applying the serum, make sure you blow-dry your hair until it is completely dry. This is important because damp hair can cause dust or grime to stick to your hair and scalp.
• If you use a hair straightener often, it is best to first apply serum and then go for the straightener. The serum will also protect your hair from any damage caused due to overheating and the resulting breakage.
• Make sure to brush your hair gently to remove any knots or tangles in the hair.

How To Pick The Right Serum For Your Hair Type

Always go for a good brand even though it may cost a little more. Trying to cut down on the cost may not be a good idea when you want the desired results for your hair.

1. While applying hair serum, make sure you don’t rub it into your scalp. Instead, comb it lightly through your hair, preferably with your fingertips or a comb.
2. If you feel your hair is drying out unusually fast after using the serum, try switching the product. It could be possible that the product you have been using is not suitable for your hair type. Switching to another brand may resolve the issue.
3. While you are using the hair serum, try other new hair products, like a new shampoo and conditioner, to understand what combination works best for your hair.
4. Using too much of anything is bad, and that holds true for hair serum as well. It is good to use the serum in moderate quantities. Try not to use it every day. If you need to use it every day, do so in small quantities..
5. Apply hair serum when your hair is damp or towel-dried and not when it is dripping wet.
6. Do not use hair serum repeatedly without washing your hair. This may lead to greasy hair and dandruff. Make sure your hair is washed and clean before using a hair serum.
7. Always look for a hair serum based on your hair type. Look for ingredients that are specially designed for specific hair types. If you have damaged hair, opt for jojoba or lavender oil-enriched hair serums. These types of hair serums are light and help to detangle your hair.
8. For thick hair types, hair serums that are enriched with Morrocan argan oil work great. For curly hair types, look for ingredients like jojoba, sweet almond, marula, and argan oils for extra hydration.
9. If you like to experiment with your hair colors or your hair is chemically treated, then opt for a hair serum with green tea extracts and coconut oil as active ingredients.

Overusing hair serum can make your hair look limp rather than voluminous. Hence, limit the amount of serum while using. Find out how much is sufficient for your hair type in the next section.

How Much Serum Should You Use?

Remember that a little hair serum goes a long way. No matter how thick or long your hair is, applying too much hair serum can make your hair look limp rather than lustrous. You should only apply a pea-sized amount for fine hair, dime-sized amount for medium-length tresses, and a quarter-sized amount for thick and long hair.

Hair Serum For Different Hair Types: Recipes

Here are three simple and effective hair serum recipes that are good for dry, oily, and brittle hair types. As these contain natural and essential oils, they will help nourish your hair.

For Oily Hair

Those with oily hair should go for a light oil as a base for making their hair serum. Oils like coconut oil and jojoba oil are lighter than other oils.

The excess oiliness of hair is caused by the excess sebumⁱ  A substance made up of fats and oils secreted by the sebaceous glands to keep the skin naturally hydrated. produced by the sebaceous glandsⁱ  Microscopic glands in hair follicles underneath the surface of the skin that produce oils to keep the skin hydrated. , which makes your hair look greasy all the time. Therefore, you should choose an essential oil that can control these glands. Lemon, peppermint, and geranium essential oils are light and suit oily hair the best.

Process

• Mix a few drops of any essential oil mentioned above with 100 ml of coconut or jojoba oil.
• Shake well and store this serum in a dark place in a tight screw-type bottle.
• Apply this oil to dry or damp hair to retain moisture and prevent excess oiliness.
• If you do not want to use it during the day (as it may make your hair look oily), you can always use this serum at night. Massage this serum all over your hair and scalp every night before going to bed.

For Dry Hair

Those with dry hair are usually prone to split ends and breakage. Thick, concentrated, and moisturizing oils like castor oil should be selected as the serum base. For dry scalps, essential oils like rosewood and lavender work well.

Process

• Mix a few drops of any of these essential oils with 100 ml of pure castor oil.
• Shake well and store in an airtight bottle.
• If you feel that the consistency of the castor oil is very thick, you can add 20 ml of coconut oil to lighten the consistency.
• A daily massage with this serum on a dry scalp can result in beautiful, lustrous, and nourished hair without any split ends or dryness.

For Brittle Hair

A concoction of lavender oil and aloe vera gel not only helps to restore health back in damaged hair but is also a wonderful remedy for brittle hair and promotes healthy hair growth.

• Pour a cup of water into a pan and bring it to a boil.
• Add a tablespoon each of dried fenugreek and fresh basil leaves to the boiling water.
• Heat this mixture for another 15 minutes. Strain it and let it cool down.
• Then, add aloe vera gel to this mixture and mix.
