If you’re anything like us, you probably have a 10-step hair care routine. However, chances are it’s still missing one crucial product: hair serum. Think of hair serum like top coat nail polish. You could skip it, but who wants a flat, dull manicure? Whether you’re looking for a new serum for your dark brown hair or have no clue what hair serum is, you’ve come to the right place.
We’re breaking down everything you need to know about hair serum and recommending some of our favorite formulas. By the time you’re done, you’ll realize why hair serum is the missing piece to your perfect hair care routine.
What is hair serum?
Hair serums are very similar to face serums in that they provide concentrated and targeted results that address many different hair concerns. Unlike hair oils, which penetrate the hair shaft, serums sit on top of the hair and coat the strands to instantly make your hair look and feel better. Most hair serums are excellent at addressing frizz and adding shine while protecting your strands from environmental and styling aggressors.
Which serum is best for your hair?
While we believe everyone should incorporate a hair serum into their hair care routine, picking the right formula for your hair is crucial. Before heading to the store, identify what hair concerns you’d like the serum to address. Are you battling frizz? Breakage? Dull, lackluster locks? Do you have thick locks? You’ll want a serum heavy enough to coat your plentiful locks. On the other hand, you’ll want a lightweight hair serum that won’t weigh down your locks if your hair is thin.
Once you’ve mulled over your concerns, think about what you do to your hair every day. Do you heat style it? If so, pick up a hair serum that doubles as a heat protectant. Do you wear your hair in the same ponytail every day? If so, pick up a strengthening hair serum to help protect your locks from constant pulling.
Are serums bad for your hair?
Whether or not a serum will work for you and your mane depends on the formula and your hair needs, but no hair serums on the market should damage your strands.
When should I use hair serum?
Most stylists agree the best time to use hair serum is when your hair is damp, right after it’s been freshly washed. The serum will have a better opportunity to address your hair concerns when it is applied to hair that’s free of other products. Apply the serum to your damp locks focusing on the mid-length and ends, the oldest and typically driest part of your hair. Give your hair a few minutes to reap the full benefits of the serum before continuing with your usual styling routine.
Hair serum can also be used on dry hair, but it can be less effective at addressing your hair concerns when it’s applied on top of other hair products. Applying hair serum to dry hair is great for anyone battling frizz, flyaways, static, and hair that looks and feel dry. If you’re suffering from any of those hair woes, simply smooth the serum over your locks until you achieve your desired look.
Because hair serums are so concentrated, it can be tempting to apply tons of product to your locks. However, less is more when it comes to hair serum. Because hair serums typically come in an oil-like formula, applying too much hair serum can not only make your hair look and feel greasy but also can lead to major product buildup.
If you’re convinced your locks need more serum than the package recommends, begin with the recommended amount and wait 30 minutes to see how your hair feels. If you still think your locks could benefit from more serum after half an hour, apply half of the recommended amount to ensure you don’t overload your hair with product.
If you accidentally pile on too much hair serum, a clarifying shampoo will bring your hair back to its former glory.
Now that you know what hair serums are and how to use them, it’s time to find the perfect one for your mane. We’ve rounded up 12 hair serums you’re bound to love.
