Even though autumn and winter are on their way and dry hair may seem to be on the horizon, you can save your strands by using hair serum. Yes, our weekends will now consist of watching Netflix with our favourite fluffy blanket, but taking care of our hair with the best hair products such as hair oil and serum is still important.

Now that the summer (which let's face it consisted of constant cover of clouds) we've now collectively decided to chill out on the hot hair tools. Now, we're giving our locks a much-needed vacation after having been exposed to the summer sun for the past few months. And no, a hair mask on its own won't be the solution to all your hair care woes.

We all know that hair serums are a pretty important step in achieving Disney Princess-esque tresses, but with lots of them out there, it can be difficult to know which is right for you. We know you're keen to improve your hair health, especially in the wake of the celeb-loved hair care product: Hair Syrup.

Editor's choice

This ultra-concentrated serum by Grown Gorgeous works to increase the thickness of each strand and stimulates hair follicles to promote hair growth. Specifically formulated for fine, thinning hair. If that's your main concern with your own hair, then this could be the perfect product for you.

Review: "Not greasy at all. Lovely fragrance. Easily applied. One bottle lasts one month. First bottle finished, no hair growth yet. My daughter has thinning hair and she says it's helped her scalp not be as greasy as before hair feels and looks "slightly" thicker. But no hair growth, not yet any way. Think it will be months before we see any real progress."

Review: "I can’t recommend this product enough! I have very long hair and hate going to the hair dressers (I go about once every 10-12 months). I bought this about 3 months ago and not even halfway thru the bottle, and I use about 8 pumps to cover my hair after every wash. Since using it my hair has grown so much longer as the ends don’t break, it’s so soft and shiny that everyone asks if I have extensions! I use a lot of heat on my hair and curl it about 4 times a week and this serum has reduced sooo much damage. I recommend it to everyone, best product I’ve ever used! After getting it cut today for first time in a year I was worried I’d need a lot off the bottom to keep it healthy but I only needed a little trim. Amazing product 10/10**."**

  • Detangles hair easily


  • Not suitable for those with nut allergies

How to use hair serum: A guide

Use on damp hair: most of the time hair serum is designed to be used on damp (not soaking wet) hair, but double-check the recommended usage on the package.

Be careful of overkill: too much product can leave hair feeling greasy, which is not an ideal vibe. Check the bottle, but one or two pumps is more than enough.

Use regularly: to reap the benefits, consistency is key. Use every time you wash your hair for the best results.

We recommend using a rosemary oil with your hair serum for best results.
