Use this comprehensive guide to learn everything about the ingredients that go into hair serums. Discover which you need and find the right serum for you.

Understanding the Ingredients in Your Hair Serum

There are endless hair serums available on the market. Each product comes with its promises — reducing frizz, adding shine, nourishing moisturization, adding volume, and often a combination of benefits. Each one also boasts the main ingredients to catch your attention. Do you really know which ingredients benefit your hair, though?

Some hair serums are full of filler ingredients or harsh chemicals. Sometimes, the boasted ingredient on the package doesn’t actually help your hair much, or it’s barely in the formula. Paying attention to the ingredients in your hair serum is vital to finding the right product for your hair. Unfortunately, a lack of regulation on hair products means you need to take some matters into your own hands.

Checking and understanding the ingredients in your hair products ensures that the serum is safe for your hair type and scalp. Some ingredients, such as alcohol, can be drying to the hair and scalp, while others, such as sulfates, can be harsh and strip the hair of its natural oils. Choose a serum for your specific hair type and concerns.

Choose a serum that aligns with your hair goals. If you’re looking for a serum to add shine, choose one that contains ingredients like argan oil or keratin. If you’re looking to control frizz, look for ingredients like silicone or behentrimonium chloride. It’s also important to learn which products aren’t suitable for certain hair types. For example, argan oil is too dark for blonde hair and often too heavy for fine hair.

Common Ingredients in Hair Serums

Learning about the ingredients in your hair serums allows you to find the best products for your unique needs and desires. Many ingredients are commonly found in hair serums that provide various benefits.

Proteins

Proteins are essential for hair health. They make up about 80 percent of the hair’s structure and give hair its strength, elasticity, and shine. Proteins fill in gaps in hair, strengthening the shaft and reducing breakage. They also increase shine, reduce frizz, and prevent hair loss.

Choose a protein treatment according to your hair type. If you have dry hair, look for a moisturizing protein treatment. If you have oily hair, use a lightweight protein. Here are some common proteins in hair serums.

Keratin

Keratin is the main protein that makes up hair, which gives it strength, elasticity, and shine.

Collagen

Collagen is another protein found in hair that gives hair its structure and support.

Silk Protein

Silk protein is a natural protein known for its moisturizing and conditioning properties. It can make hair softer, smoother, and more manageable.

Wheat Protein

Wheat protein is a plant-based protein known for its strengthening and repairing properties. It helps make hair stronger and less prone to breakage.

Soy Protein

Soy protein is another plant-based protein known for its moisturizing and detangling properties. It can help to make hair softer, smoother, and easier to manage.

Vitamins

Vitamins nourish the hair and scalp. Vitamins should primarily come from your diet, but topical treatments are beneficial to your hair and scalp. See which vitamins you may need.

Biotin

Biotin is essential for the production of keratin, the protein that makes up hair. Biotin deficiency leads to hair loss, breakage, and thinning.

Panthenol

Panthenol is a form of vitamin B5 that can help to moisturize and repair the hair. It can also help to protect the hair from heat damage.

Vitamin A

Vitamin A is essential for cell growth and repair. It’s involved in the production of sebum, which is the oil that keeps hair healthy. Vitamin A deficiency can lead to dry, brittle hair.

Vitamin C

Vitamin C is an antioxidant that protects hair from damage and helps produce collagen, a protein that gives hair strength and elasticity. Vitamin C deficiency can lead to hair loss and breakage.

Vitamin E

Vitamin E is an antioxidant that protects hair from damage and helps produce new hair cells. Vitamin E deficiency can lead to dry, brittle hair.

Folate

Folate, also known as vitamin B9, is essential for cell growth and repair. Folate deficiency can lead to hair loss and breakage.

Iron

Iron is essential for the production of red blood cells, which carry oxygen to the hair follicles. Iron deficiency can lead to hair loss and thinning.

Zinc

Zinc is essential for cell growth, cell repair, and the production of new hair cells. Zinc deficiency can lead to hair loss and breakage.

Sealants

Sealants come in a variety of forms, including butter, oils, and silicones. Sealants lock in moisture to prevent the hair from getting dry and damaged. They create a protective barrier around the hair to protect it from heat-styling tools. Sealants also smooth down hair cuticles to reduce frizz, seal the ends of hair, prevent split ends, and add shine to your hair. Plus, these products make hair more manageable and less prone to tangles.

Shea Butter

Shea butter is a natural butter that is rich in fatty acids. It’s moisturizing and protective.

Cocoa Butter

Cocoa butter is a natural butter extracted from the cocoa bean. It’s rich in fatty acids and vitamins to moisturize hair, make it shiny, protect it from heat, and reduce frizz.

Mango Butter

Mango butter is a natural oil that moisturizes the hair, protects it from heat damage, reduces frizz, and adds shine. It also contains antifungal and anti-inflammatory properties to soothe the scalp and treat dandruff.

Honey

Honey is a natural humectant that can help to attract moisture to hair. It can also help to add shine to hair.

Glycerin

Glycerin is a humectant that helps to attract water to the hair. This can help to keep the hair hydrated and prevent it from drying out.

Ceramides

Ceramides are a type of lipid that helps to protect the hair from damage. They can also help to keep the hair hydrated and prevent it from frizzing.

Silicones

Silicones are synthetic polymers that coat the hair to make it smooth and shiny while taming flyaways. They also protect the hair from heat damage. Silicones moisturize hair to make it feel softer and more manageable. However, silicones can build up on the hair and scalp over time, making it difficult to style the hair.

The use of silicone in hair products is quite controversial. Some people love it, and others believe it dries hair out over time. The FDA approved the use of silicone in beauty products, and there are no known risks to your health. However, some studies suggest there may be a negative impact on the environment and fish from using silicone.

According to dermatologist Dr. Jennifer Trent, “If you have decided to avoid silicones in your hair and skin care products, there are alternatives. For the hair, you can try plant-based oils and butter (jojoba oil or shea butter) to moisturize and strengthen the hair and give it a smooth, soft texture.”

If you want to test and see if silicones are right for you, choose from one of these two categories:

• Water-soluble silicones: These silicones are easily washed away with water and — therefore — less likely to build up on the hair and scalp. They moisturize hair while making it smoother and more manageable.
• Non-water-soluble silicones: These silicones aren’t easily washed away with water, so they may cause build-up on the hair and scalp over time. They protect hair from heat damage and make it appear shinier.

Natural Oils in Hair Serum

The main focus of many hair products is oil ingredients. Many oils offer a range of conditioning properties and protect from heat damage. Find one — or several — that suit your needs.

Argan Oil

Argan oil is a Moroccan oil rich in vitamins and antioxidants known for its moisturizing and conditioning properties. It makes hair softer, smoother, and more manageable while protecting it from heat damage.
