Find your gearWhat is Hair Serum?
Hair serum is a leave-in product designed to add shine, reduce frizz, and enhance the overall appearance of your hair. Most serums contain ingredients like silicones, essential oils, and proteins that coat the hair shaft, helping to smooth the cuticle and protect the hair from environmental stressors. Hair serums can be used on damp or dry hair, depending on the product’s formulation, and they are great for tackling issues like dryness, split ends, and lackluster hair.

Choosing the Right Serum for Your Hair Type
The first step in choosing the best serum for your hair is understanding your hair type and its specific needs. Hair care products are not one-size-fits-all, so finding the right formula can make all the difference.
1. Serums for Fine or Thin Hair
If you have fine or thin hair, the main concern is weight. Thick, heavy serums can weigh your hair down, leaving it looking flat and greasy. Instead, opt for a lightweight serum that nourishes your hair without making it greasy.
Product Recommendation: Ouai Fine Hair Serum
Ouai’s Fine Hair Serum is a fantastic option for those with thin or fine hair. This serum is packed with nourishing ingredients like ginger root extract, chia seed oil, and vitamin E. It’s designed to give your hair a boost of hydration and shine without weighing it down. It also helps to protect hair from heat styling, making it ideal for daily use. A little goes a long way, so you don’t need much to keep your hair looking shiny and healthy.
How to Use: Apply a small amount to damp hair, focusing on the mid-lengths to the ends. Blow-dry or air dry as usual.
2. Serums for Curly Hair
Curly hair tends to be dry and prone to frizz due to its natural structure. Curly hair requires a serum that provides moisture and control while helping to define curls and fight frizz.
Product Recommendation: DevaCurl SuperCream Coconut Curl Styler
The DevaCurl SuperCream Coconut Curl Styler is a nourishing serum that’s perfect for curly hair. It’s formulated with coconut oil, which helps to hydrate curls, and it provides a soft hold that defines curls without the crunch. This serum is ideal for enhancing the natural texture of your curls while fighting frizz and adding shine.
How to Use: Apply a generous amount to damp hair and scrunch to define your curls. For extra definition, you can diffuse your hair or allow it to air dry.
3. Serums for Dry or Damaged Hair
If your hair is dry or damaged from coloring, heat styling, or environmental factors, you’ll need a serum that deeply nourishes and repairs your hair while adding moisture.
Product Recommendation: Moroccanoil Treatment
Moroccanoil Treatment is a cult favorite that’s beloved for its deep hydration and reparative qualities. It contains argan oil, which is rich in antioxidants, vitamins, and essential fatty acids that help repair and hydrate dry, damaged hair. It also adds a beautiful shine and makes hair easier to detangle. This serum works on all hair types, but it’s especially beneficial for dry and damaged hair.
How to Use: Apply a few drops to damp hair, focusing on the ends. You can also use it as a styling aid to smooth out frizz or add shine to dry hair.
4. Serums for Oily Hair
For those with oily hair, choosing the right serum can be a bit tricky. You want to add shine and hydration without making your scalp greasy. Lightweight serums with oil-absorbing properties are ideal for this hair type.
Product Recommendation: Bumble and Bumble Hairdresser’s Invisible Oil
Bumble and Bumble’s Hairdresser’s Invisible Oil is a weightless serum that provides hydration while controlling frizz. It’s formulated with a blend of six oils, including coconut, argan, and macadamia, but it’s light enough not to weigh down oily hair. This serum smooths and nourishes the hair, leaving it soft, shiny, and manageable without looking greasy.
How to Use: Apply a small amount to damp hair, concentrating on the mid-lengths and ends. Avoid applying too much to the roots to prevent excess oil buildup.
5. Serums for Thick or Coarse Hair
Thick and coarse hair often requires a serum that offers extra moisture and control. These hair types tend to absorb product quickly, so look for serums with more substantial formulations that provide long-lasting hydration and taming benefits.
Product Recommendation: Kérastase Elixir Ultime Oil Serum
Kérastase Elixir Ultime Oil Serum is a luxurious serum that’s designed to smooth and control thick or coarse hair. Its blend of four essential oils, including argan, camellia, and maize oils, provides intense nourishment, leaving the hair feeling soft and manageable. This serum also offers heat protection, making it a great choice for those who regularly style their hair with hot tools.
How to Use: Apply a few drops to damp hair before blow-drying or styling. For dry hair, apply a small amount to the ends for added shine and smoothness.

6. Serums for Color-Treated Hair
Color-treated hair requires special care to maintain its vibrancy and prevent further damage. Color-treated hair can become dry, brittle, and prone to breakage, so look for serums that offer both hydration and protection against UV damage and heat styling.
Product Recommendation: Redken Color Extend Magnetics Mega Hair Serum
Redken’s Color Extend Magnetics Mega Hair Serum is perfect for color-treated hair. It helps to lock in color and prevent fading, while also providing intense moisture and shine. The formula is enriched with amino acids and protein, which help to strengthen and protect hair, reducing the risk of breakage.
How to Use: Apply to damp hair, focusing on the ends and any areas that are most prone to damage. Style as usual.
How to Apply Hair Serum Effectively
No matter your hair type, applying serum correctly is crucial to achieving the best results. Here’s how to get the most out of your hair serum:
- Use a Small Amount: Hair serums are concentrated, so a little goes a long way. Start with a pea-sized amount and add more if needed.
- Focus on the Ends: Most hair serums should be applied to the mid-lengths and ends of the hair, where dryness and damage are most likely to occur.
- Avoid the Scalp: While it’s tempting to apply serum to the scalp, it can lead to greasiness. Keep the serum focused on the lengths and ends of your hair.
- Distribute Evenly: Use your fingers or a wide-tooth comb to evenly distribute the serum throughout your hair to ensure every strand gets the benefits.
Whether you’re battling frizz, dryness, or damage, there’s a serum out there to help address your unique hair concerns. By choosing a serum tailored to your hair type, you can achieve smoother, shinier, and healthier hair. Don’t be afraid to experiment with different products until you find the one that works best for you. With the right serum in your hair care arsenal, you’ll be able to achieve beautiful, healthy hair every day.
