How to choose the right hair extensions

Which colour should I choose?

It’s best to choose a colour as closely matched to your own hair for best results, however it doesn’t need to be matched perfectly to blend in well and be undetectable. If you’re having trouble choosing please see our colour guide here or send us some pictures of your hair colour taken in natural light using our colour match serviceWe can also custom make any product specifically how you need.

How many will I need?

Weights are shown for each extension type we sell on their product description pages. To add some volume to your hair about 50 grams will be needed (a half head).  A standard full head is 100 grams and is enough to add both volume and length to hair that is thin- medium in density and has some length already. 

More hair will be needed if you have very short or thick hair or if your natural hair is cut blunt. You will need 100- 200 grams.

How long does my hair have to be to have extensions?

We recommend your natural hair be at least 10cm (4 Inches) long to be able to conceal the hair extension attachments for whichever method you choose.

If you have quite short hair you will need a hairdresser to trim and blend your extensions in with layers by razor cutting them in after applying.

How to care for your hair

How long will my extensions last?

How long your hair extensions last depends greatly on your care regime and lifestyle. Clip in extensions will last longest as they’re not usually worn daily and require less frequent washing. Average use of our more permanent methods including tape hair, microring and weaves is 2-6 months, however some customers get up to a years use from our extensions following our care advice.

Can I colour/ bleach/ tone my hair extensions?

It’s best to choose a colour as closely matched to your hair as possible so that colouring is not needed, however the extensions are human hair and can be coloured.

We use remy hair for all our extensions. The hair is initially all dark brown to begin with and is bleached right back to blonde for most shades, particularly the shades lighter than medium brown. The hair is then dyed to the required shade. For wavy hair the wave is permed into the hair. These processes can be a little harsh on the hair and for that reason we don’t recommend further bleaching. 

If you need to colour or tone the hair it’s best to use a semi permanent dye as these are much more gentle. You can use permanent to go darker, however it will reduce how long your extension last. Always perform a small test first. 

Medusa will not refund on a product that has been toned or coloured resulting in an undesirable effect or hair condition. The hair can be coloured at the buyers risk and Medusa will not be held accountable for results.

Can I swim with my hair extensions?

You can swim wearing your hair extensions however salt and chlorinated water will affect how long your extensions last. If you do swim wearing extensions it’s important not to let the salt or chlorinated water dry in your hair. Rinse well straight after swimming with clean water.

Can I perm my hair extensions?

It’s not recommended but you can perm your hair extensions. Bear in mind it will affect how long your extensions last.

We use remy hair for all our extensions. The hair is initially all dark brown to begin with and is bleached right back to blonde for most shades, particularly the shades lighter than medium brown. The hair is then dyed to the required shade. For wavy hair the wave is permed into the hair. These processes can be a little harsh on the hair and for that reason we don’t recommend further perming… but it can be done

What products should I use on my hair extensions?

It is important to use quality products on your extensions, especially the types worn for longer periods as opposed to clip in extensions that require less frequent washing as they’re usually not worn daily.

Using a shampoo free from sodium laureth sulphate (common foaming agent) will extend the life of your extensions and prevent them becoming dry.

We stock X-Ten shampoo, conditioner, treatments and styling products made by Natural Look, an Australian company. They’re designed specifically for extensions to address the common issues experienced like the need to preserve and provide moisture, eliminate frizz, and give shine.

How do I remove my hair extensions?

Clip in Extensions – Bends clips backwards to open and slide out of hair.

Microring, Easy Weft Method & Feather Extensions – Use extension pliers to squeeze microring back into the open position and slide out of hair.

Sewn in Weft – Use small scissors to snip along the sewn thread and slide out of hair.

Tape Hair Extensions – Pour a little of our tape hair remover on each tape pair, leave for a minute and peel apart. If any residue is left dust a little cornflour… yes cornflour! onto each section and comb through with a fine toothed comb. Shampoo hair twice and condition.
