Hair Extensions Quick Care Guide

Key Things to Look for –


The ingredient is an important part of choosing the correct shampoo and conditioner.

Choosing organic and natural shampoos is a great start, as they are automatically gentler to the hair extensions and keep them safe.

Choosing one with no sulfate is crucial, as sulphate strips the chemicals in the extension.

The high level of salt makes them fall out a lot quicker. So, choose sulphate-free and your hair will thank you for it!

Hair Type

Consider your own hair type before purchasing your shampoo and conditioner.

The type of your hair will rub off on your hair extensions, determining what hair type your extensions will be.

If you have greasy oily hair, then in the end your hair extensions will be the same.

So, it is important to still buy the best shampoo for your hair to keep your hair extensions healthy.


Consider the quality of the brand before purchasing any shampoo and conditioner for your hair extensions.

If you have spent a lot of money on your extensions but then buy a cheap shampoo and conditioner to care for them, then they are not going to last as long.

How to Wash your Hair Extensions –

Be Patient

It is important if you choose to have glue in extensions you do not wash your hair for at least 3 days.

If you wash it before the extensions are fully set in place, then you risk weakening the glue and loosing hair from the extensions.

If you have clip in extensions that you can simply add in and remove, we suggest taking them out when having a hair wash and simply washing your extensions separately.

This way you can really scrub the scalp and remove any dead skin or dirt from your hair.

If you have had them professionally fitted such as micro rings, it is still suggested to be gentle when washing your hair with these in, to make sure you do not weaken the attachment part of the extension.

Use Warm Water

It is recommended to use lukewarm water not extremely hot water as this can cause damage to extension, especially the synthetic type.

Avoid Using Heated Tools

Its important you understand the type of extensions you own. Using heated tools like hair dryers and hair straighteners on human hair is no problem at all and will not cause any damage. 

Whereas ‘most’ Synthetic style hair extensions will melt at the first sign of this type of heat.

Not all Synthetic hair will melt, as some will be heat treated and will be safe to style with this amount of heat, make sure you check before using any tool on your extension.

Do Not Sleep with Your Hair Wet

Its important to dry your hair before sleeping as this is when you are most likely to cause tangles in your hair when you are laying on it.

Leaving it wet and laying on it only makes matting and tangling worse.

Frequently Asked Questions –

Can I use Normal Shampoo on My Hair Extensions?

Yes, its likely you can use your own shampoo on your extensions, or simply a shampoo you may have in your house.

If it is a gentle shampoo like baby shampoo, then it is likely to have no damaging ingredients within the shampoo.

If the products are sulphate free (which many are), you are safe to use it on your extensions.

Why do my hair extensions get matted?

There are a few reasons why your extensions are becoming matted. If they become dry and frizzy over time, then this will encourage the tangles. This can be sorted with a simple hair mask to regenerate the hair.

It could also become more matted when the hair is loosing its natural oils, which could mean its time to buy your next set.

How often should you wash your hair with hair extensions?

If you have Synthetic hair extensions, it is suggested you wash your hair every 30 wears (as little as possible).

Or if they become tangled and matted before the 30 wears you may need to give in and wash them before.

If you have Human hair extensions, then you need to wash and treat them as you would your own hair.

This differs depending on your hair type whether it is dry or greasy and how often it needs washing, so this is down to personal preference.

If you Have Hair Extensions Should You Sleep with Your Hair up or Down?

It is better for your extensions if you can go to sleep with your hair tied up, as many extensions are delicate, and it does not take much for them to tangle and become matted.

Can you brush your hair when you have extensions?

Yes, it is important to brush your hair daily when you have extensions, but its important to never brush your hair wet, as this is when your extensions are most susceptible to breakage.

It is also recommended to use the correct brush with your hair extensions or even a wide tooth comb to make sure you do not pull out any hair whilst brushing.


Looking at the shampoo and conditioners we have recommended, there really is a product for everyone no matter what type of hair extensions you have.

We also have reviewed different types of price ranges and different hair types. So, find your hair type and your budget and choose your extensions new best friend.
