Hair oils: they’re the simple route to softer, sleeker locks. All you have to do is slather your strands, sit back and wait for them to work their magic, right?
Not quite. While they may seem pretty straight-talking, the world of oil-based hair treatments can get a little overwhelming, especially if you’re not too familiar with the ingredients – pick the wrong formula and you might just end up with hair oilier than the bottom of a chip fryer (eek)!
In a bid to help you save your coin, time and strands, we've rounded up the best hair oils and matched them to each and every hair type. But before you pick your potion, here's a 101 guide to using hair oils and serums.
What is hair serum?
Hair serum is a treatment that is liquid-based and can be used in tandem with other hair care products, aiming to add shine and nourishment to your strands. Its primary function is to coat the hair in a protective glaze that adds shine whilst in some cases delivering a specialised dose of nutrients (e.g. some serums are created to encourage hair growth).
How does hair growth serum work?
A hair growth serum won't directly increase hair growth, but it can support the hair follicles to grow thicker and shinier than usual which should improve the overall look of your 'do. Some hair growth serums work by focusing on the scalp and increasing blood flow to the scalp, which in some instances can encourage a healthy environment for hair to grow. However, it is important to note that how quickly hair grows is usually predetermined by your genetics, and no amount of serum can drastically change this.
How do you use hair serum?
You can use hair serums on pre-washed, post-washed or styled hair to smooth down flyaways – there really is no incorrect way to apply it! The latter is the most popular way as it adds shine and smooths down that unwanted frizz without drastically weighing it down.
Depending on your hair type, you should aim to use around two to three drops of your chosen oil or serum and apply it to the mid-lengths and ends. Applying these products to the roots will only create a greasy scalp which will then cause you to indulge in over washing your tresses. It can be applied to wet or dry hair based on your personal preference.
What are the effects of different hair oils?
The effects of different hair oils include boosting growth, taming frizzy hair, accommodating sensitive skin, beating dandruff and fixing up severely dehydrated hair types. For example, argan oil is renowned for kicking dry hair to the curb, whilst baobab oil has been known to sometimes boost hair growth. Almond oil is loved for its effect on dandruff, and coconut oil is an all-rounder oil that pretty much tackles all of your major hair woes.
Overall, most hair oils share the same aim of smoothing out frizz whilst nourishing dry hair types, but some oils are better at different things. Different hair types require different hair oils, too.
