What are hair serums?

They are a cuticle-sealing, shine-giving miracle frizz taming remedy. What it isn’t, is an oil like olive oil or coconut oil. It’s a liquid-based silicone styling product made to smooth, shine and coat your hair shafts with goodness.

It works differently to oil in that it coats to outside of your hair, whereas oil sinks in and penetrates your hair fibre – adding shine, smoothness, hydration, and humidity protection.

They can be applied to wet hair, damp hair or dry hair, as both a pre-styling treatment and a finishing solution. They’re suitable for all hair types too. Making it a versatile, handy product for in between washes and touch ups on the go.

What do hair serums do?

They coat your hair without dulling its colour. Giving it a super shine and an extra protective barrier against the elements.

Their protective barrier can be used as a quick-fix to control frizz, damaged hair, flyaways and the dreaded, haystack hair. It’s an essential for keeping coloured locks smooth and silky. As with most styling products, it’s all in the application.

How do I use hair serums?

These slippery miracles come in all shapes and sizes of density and thickness. So you can choose the levels of coating you need based on the condition of your hair and what you want it to do.

The right one for you and how you use it comes with trial and error. Here are a few do’s and don’ts to get you going.

Do:

  • Use it after styling to control flyaways and smooth frizz.
  • Use it before drying your hair for heat protection.
  • Apply it to the mid-lengths and ends of your hair, where your hair is older and will have more damage.
  • Choose the right density for you hair.

Don’t:

  • Don’t apply too much. You’ll risk your hair looking greasy.
  • Don’t apply it straight out of the bottle. Warm it in between your fingers first to make sure it goes a long way.
  • Don’t apply it to unwashed hair. It forms a protective layer so any dirt or dust on your hair will get locked in.
  • Don’t apply it to your roots – this will make your hair look super greasy!

Top tips from the professionals.

Are hair serums good for coloured hair?

Hair processing and colouring can make your ends dry and your hair’s overall sheen flat. They can lock in your colour to prevent dulling, fading, and damage. 

Picking which one is right for you depends on the condition and thickness of your hair.

If you have thin hair, you may want to try a thickening one, or a lightweight one that won’t weigh down your hair.

If you have thick, dry hair, these products are made for you!

There are even solutions that enhance curls in curly and wavy hair.

For us coloured hair lovers, we need colour protection and have shiny hair goals. If you style your hair often, they will also protect against damage due to heat. 

Is serum good for bleached hair?

I’m sure you’ve heard that if your hair is bleached, it should only be dyed with colour that has been tested for use on chemically-treated hair. But did you know this also applies to beauty products?

If your hair is damaged and dry, a this may be the perfect solution.

Bleaching your hair removes natural oils and proteins which can cause dryness. Serum helps to replenish what was lost during bleaching while adding shine back into your locks.

They coat the hair strand and give it a smooth, sleek finish. They can also add shine to your locks by restoring moisture and softness. Everything bleached hair needs.

What is the best hair serum for coloured hair?

There are several different types on the market, but not all will work for you depending on what your specific needs may be. You’ll want to experiment with different options until you find one that suits your hair type and lifestyle.

From smoothing anti-frizz to ramping up the high-gloss shine, here is the best serum for coloured hair you need to keep your dyed locks looking fabulous!

Best for: Long lasting shine.

#1 Kerastase Reflection Chromatic Fluid.

q? encoding=UTF8&ASIN=B07232JHWQ&Format= SL250 &ID=AsinImage&MarketPlace=GB&ServiceVersion=20070822&WS=1&tag=colouredhairc 21&language=en GBkerastase fluid

Reviewers say:

“Kerastase Chromatique products deliver on the shine and smoothness they promise for colour treated hair. It is like having brand new hair switching to this!”

“I’m addicted to this product for my long hair and curls. You can feel and see the effects immediately. It makes a super nice shine, I will be coming back for more! ;)”

“I bought this and carry it around for the gym. I’ve also used it in humid weather and before straightening. It doesn’t feel greasy at all. Highly recommend it to anyone with dyed hair.”

We say:

We’ve loved Kerastase forever and their colour shampoo and conditioners have long been a must-buy for us with their unique restorative powers. This is a great addition to the must-have list.

It left our hair feeling soft without any residue. You have to use it sparingly as it’s super concentrated. So it goes a long way, but probably best for thicker hair.

“This product is great it does exactly what it says. It really helps to keep your hair soft, shiny and manageable.”

“So impressed with this product that I ordered the larger bottle so I don’t run out. Love WOW.”

We say:

Color WOW have coloured hair products nailed. Their root cover up and conditioner top our Best Of Lists year on year.

It makes your hair smooth and shiny and lasted after one wash on our colour treated hair. This tops the list for us.

Best for: Long lasting shine.

Reviewers say:

“I’m a 25 year old woman, and whether from using heat tools or colouring my hair a lot, my hair had started to really thin above my temples. Now you would never know. It does take time but long term usage definitely pays off.”

“I use this almost every night before bed, and I can see that my baby hair has finally started growing longer. The good thing is that it doesn’t leave the hair greasy.”

“I have a very itchy, flakey, irritated scalp, so I got this to moisturise and exfoliate. When I use this regularly I notice a lot less hair shed and my scalp has no itchiness or flakes. I can also go longer in between shampoos now!”

We say:

Stripping back unnecessary packaging and surplus ingredients, The Ordinary has shaken up the skin care industry with their high-performing products. Now they’re turning their attention to hair and as big fans of their skin care, we had to give this hot new product a go.

Promising thicker, denser, fuller and healthier hair, this concentrated formula is different from a styling product. It unites natural extracts, peptides and caffeine to nourish your hair from root to tip.

We found it worked wonders on our scalp which was dry from all the processing it goes through. Use this to keep your hair and scalp healthy and in the best condition for colour.

Best for: Healthier hair and scalp.

#4 L’Oreal Serie Expert Serioxyl Denser Serum

q? encoding=UTF8&ASIN=B00NU4LW00&Format= SL250 &ID=AsinImage&MarketPlace=GB&ServiceVersion=20070822&WS=1&tag=colouredhairc 21&language=en GBloreal serie expert serum

They say:

  • A super solution that’s suitable for women and men who have very fine or thinning hair, or suffer from hair loss.
  • Protects against oxidative stress.
  • The formula will leave your hair looking denser and feeling fuller.

Reviewers say:

“I don’t know exactly how it works but I do think that my hair looks fuller and I’m sure that the shedding is less.”

“I highlight my hair every couple of months and this has been a godsend.”

“After using this for about month and half, I realised my hairs looked thicker and many new hairs are growing. I would highly recommend this product.”

We say:

One of the facts of life we live with at Coloured Hair Care is hair breakage. The processing and dyeing, straightening, crimping and waving we love to do plays havoc with our locks and makes them prone to breaking.

This one is a heavily formulated wonder potion to help your hair grow thicker and denser, with less breakage. You don’t have to be losing hair to try this, it’s great for repairing damage in places where your hair naturally thins. Finer hair, this is the one for you.

Best for: Thickening up fine hair.

We say:

Back to styling serums and this one smells amazing! It’s thinner than some of the others on the list but it really feels like your hair is drinking it in.

It gives instant smooth and a high-gloss shine. And it’s cheap as chips to boot.

Best for: Superior shine on a budget.
