We all have bad hair days (some more than others…) but we can usually get things under control after working a bit of our usual magic. Sometimes, however, that wild frizz can prove to be a difficult beast to tame, and we must turn to other methods for help.  This is where we look to the heavens and ask the question, does hair serum work?

Anti-Frizz hair serum is proving itself to be somewhat of a miracle worker. So, is it all that it’s cracked up to be? We decided to take a deep dive to find out.

What is anti-frizz hair serum and how does it work?

Anti-frizz hair serums are designed to do exactly as their name suggests, to calm down those frantic and frustrating strands and restore overall balance in the hair.

Generally speaking, hair serum is a water-based treatment made from silicones that, when applied, act to create a strong protective layer to cover the hair fiber. Not only can this help with reducing frizz, but the smooth finish gives the hair a healthy and shiny appearance. Additionally, the serum can also help shield hair from heat damage that may be caused by straighteners and curling irons, along with various environmental threats such as dirt, pollution, sun rays, and more.

How to use anti-frizz hair serum

Sounds great, but how do we get the rest results possible? Learning how to apply the hair serum correctly can be the thing that determines just how effective it will be.

Follow our handy and simple guide below to get the most out of your hair serum.

  1. Make sure your hair is very wet.
  2. Squeeze a penny-sized portion of serum into the palm of your hand.
  3. Rub your hands together to create friction, this will suitably warm the serum up.
  4. Apply the serum evenly throughout your hair.
  5. Gently distribute it among the hair roots, don’t be too forceful.
  6. Once completed, do not rinse out. Allow the hair to dry and style it as normal.

These simple steps will ensure the correct application method for the serum and will give the hair the best chance of reaping its rewards.

However, here’s an important note:  Everyone’s hair type is different, therefore products like hair serum may work better for some than for others.  For a detailed guide on hair types and where your hair might fit in, read our helpful article on the matter by clicking here.

When is the best time to use anti-frizz hair serum?

This completely depends on you and your lifestyle. However, we’d suggest using hair serum straight after showering and washing of the hair. It is best applied on wet hair, as this makes it easier for the ingredients to latch onto the strands. From that point, the hair can be dried and styled as normal.

If you want to give your hair the best protection possible, we’d recommend applying the serum in the morning before your day really begins. This will allow the serum to form that much-needed protective layer that will combat the various environmental challenges the hair will have to face over the course of the day. Tactically, this is the best time to use it.

A Closer Look at the Ingredients in Hair Serum

Understanding what type of powerful ingredients make up a hair serum is crucial to making the best product choice for your hair. Here are some typical ones:


Let’s kick things off with silicones. These are a big deal in hair serums. They envelop your hair strands, creating a smooth, shiny, and protective coating. It’s like a superhero shield for your hair, bouncing off environmental damage and heat from your styling tools. On the flip side, overuse can lead to a build-up that may weigh down your hair. So, balance is key.

Vitamin E

Next up, Vitamin E. This guy is known for its antioxidant properties. It combats those naughty free radicals from pollution and UV rays, helping to protect your hair. Plus, it aids in moisturizing your strands. After all, who doesn’t love a two-for-one deal?

Argan Oil

Now, let’s chat about argan oil. You’ve probably seen this ingredient pop up in a bunch of hair care products. And for good reason! It’s bursting with fatty acids and Vitamin E. Together, they nourish your hair, keeping it healthy, shiny, and frizz-free. Remember, a little goes a long way.

Castor Oil

Onto castor oil. This one is a heavy hitter for promoting hair growth. It’s believed to boost blood circulation in your scalp, which can encourage those follicles to produce more hair. So, if you’re looking to add some volume to your locks, keep an eye out for this ingredient.


Finally, let’s talk panthenol. It’s a form of vitamin B5 and is a hydrating superstar. It binds to the hair shaft, locking in moisture and adding a glossy sheen to your tresses. Moreover, it’s super gentle, making it a great option for those with sensitive scalps.

DIY Hair Serum Recipe

Here at Speaking Skincare, we’re all about DIY hair and skin care. So we’d be criminals if we didn’t present you with an amazing homemade hair serum recipe just for you!

Grab these…

First off, you’ll need some jojoba oil. This little gem is a crowd-pleaser for almost all hair types. It mimics the natural oil sebum, which your scalp produces. That means it hydrates your hair without making it greasy. Perfect, right?

Next on the list is grapeseed oil. It’s lightweight and packed with antioxidants, helping to protect your hair from environmental stressors. It also adds a wonderful shine to your locks.

Last but not least, you’ll need some essential oils. Lavender and rosemary are popular choices because they not only smell fantastic, they also promote hair growth. Remember, essential oils are potent, so a few drops will do.

Do this…

Alright, ready for the action? Here’s a quick and easy step-by-step guide to make your homemade hair serum:

  1. Take two tablespoons of jojoba oil and two tablespoons of grapeseed oil. Mix them in a small bottle.
  2. Next, add 5 drops each of lavender and rosemary essential oils.
  3. Shake the bottle well to mix all the ingredients together.

Voila! You’ve created your very own hair serum. Apply it to your damp hair, focusing on the mid-lengths and ends, steering clear of your scalp. It’s your homemade solution for shiny, happy hair!

Remember, the beauty of DIY is that you can tweak the recipe to suit your hair needs. So feel free to experiment and find what works best for you. Happy mixing!

The potential disadvantages

As we always say, nothing in life is perfect, and hair serum is sadly no exception. While most people will experience fantastic overall benefits, some of us won’t be as lucky. Here are some things to look out for.

People with naturally oily hair may want to reconsider the use of hair serum. Since their hair is already holding too much moisture, the addition of serum may only contribute to that problem. Having too much oil or product build-up in the hair can lead to greasiness and scalp irritation, as the substances can block vital pores which can then lead to breakouts. Opt for a softer product if this applies to you.

Next, hair serum should never be directly applied to the scalp. The scalp is one of the most sensitive areas of skin on the entire body, and it can react very easily to many types of products. Hair serum may cause inflammation of the scalp, as well as increase the risk of uncomfortable itchiness and further breakouts. Refer to our hair serum application guidelines above in order to make sure you are using the product correctly and safely.

For those that are worried about these potential issues, you may instead want to consider taking hair vitamins.  Read our handy article discussing the benefits of hair and nail vitamins by clicking here.

In conclusion

Hair serum can be a powerful tool to control wild frizz and improve the overall strength and appearance of hair. With its silicone-fuelled functionality, it can graft an essential protective layer over the hair that can help protect it against various harms and damages.

Be sure to take note of your hair’s current condition and type, as hair serum may not be suitable for everyone.
