"The best hair tips for your hair type"

Everyone’s hair is different, and we all have our individual internal guidelines on how regularly to wash our hair. We all have that friend who swears by washing her hair only once a week, or you may be that person who needs to wash their hair daily. Whatever the right answer is, there’s so many contributing factors, and it all really comes down to your hair type, lifestyle and personal preference!






Why does hair type matter?

Well here’s why. Every hair is different, from the texture, to the fineness or thickness, and even how sensatised your hair is (heat styling, hair colouring, hair lightening etc). Generally hair that is thicker tends to be drier and can go without a wash for longer. Finer hair tends to get oily faster as the oils in your scalp travel down the hair much more quickly.

Another factor is how often you work out or get sweating. If you have fine, thin hair then generally after a workout it’s going to look flat and start to look dirty after 24 hours. On the other side, if you have thicker or curly hair, you may not notice this at all, and be able to go 3 days before needing a wash.


You shouldn’t overdo it, whatever your hair type

Washing your hair too often removes the natural oils on your scalp and hair causing hair to dry out quicker. This can also push your scalp into overdrive to produce more oil, and in return makes your hair oiler over time.

Over washing can also make you hair frizzier, as the natural oils smooth the cuticles out. You’ll actually find if you wash your hair less frequently, the frizz and oiliness should decrese.

Well, what’s the answer?

IIn short, there’s no real one-size-fits-all answer for everyone. As mentioned, it depends on your hair thickness, scalp oiliness, lifestyle, and personal preference! You really just have to find what works for you, and go with that. What will also help, is using a shampoo and conditioner that’s right for you.


What’s right for me?

Oily hair tends to be finer (the actual hair cuticles), and you can have thick hair that’s ‘fine’, it just means that you have more actual hair. For those with oily hair washing it more often, I’d recommend Garnier Oily Roots Dry Ends Shampoo and Conditioner. It helps rebalance the scalp, while repairing and nourishing ends!

Thick or dry hair, tends to have more dense hair cuticles. This means that frizz can be a problem, and you have trouble smoothing it out. Garnier Sleek and Shine smoothes and nourishes the hair, while also protecting it from frizz and humidity. There’s also a version for fine hair!




Fine hair tends to go flat and lose it’s ‘oomph’ after 24 hours, resulting in you wanting to wash it to give it a vamp! Try something like Garnier Full and Luscious. These products contain a fibre-filling molecule that penetrates into the hair fibre and expands it, creating thicker hair after each wash!

Coloured or over-processed hair tends to fade, lose it’s shine and become dry. Garnier Colour Last helps to fight the colour fade-out and restore colour. It also nourishes the hair cuticles, so your hair is soft and silky. This is one of my favourites!
