Yes it absolutely can - straightened, curled, blown out - you name it. Just like our own hair, your extensions are susceptible to heat damage and loss of curl pattern, so we recommend applying a heat protectant to preserve the hair health if you are going to apply heat tools.

We have designed our textures to give you the full range of hair states with ease. For example, we love that Think Kink can be straightened to give a fluffy Press’d vibe but revert back to its kinks. However, if you know you want to straighten your Think Kink  every day  it’s probably best to just get Press’d so as to not over process your Think Kink hair (and to save some time in straightening it!). Or of course you can do like us and get both for ultimate range and ease!

The short answer is yes. However, keep in mind that colouring human hair extensions requires the same TLC as colouring your own hair, and any dyeing you do is at your own risk.

Whenever you apply a light colour dye, the hair is slightly damaged in the process and can suffer loss of curl pattern/hair loss. This is because the chemical process of lightening hair means you are removing proteins and melanin from the hair, which weakens it. 

For best results, we recommend giving it over to a professional who is familiar with colouring curly and coily hair, to ensure that your hair is under the best care.

Absolutely - just be sure to take care of your extensions afterwards by carefully rinsing the chlorine/salt water out and applying a good deep conditioning treatment. This is important because salt water and chlorine can impact the quality of your extensions, stripping them of essential moisture that can lead to a loss of softness and shine, as well as increased matting/tangling.

You sure can, though we’d recommend using a silk/satin bonnet or silk/satin scarf to preserve the quality, hair health and longevity of your extensions whilst you sleep.

If you're likely to forget to put on a satin bonnet, a satin pillowcase is a great alternative to help maintain the quality of your extensions and prevent any unnecessary tangle, shedding or matting caused by sleeping in your extensions.

The advertised length of our hair is based on the stretched length of the hair - as in the length when you pull on a hair strand. However, similar to real kinky/curly hair, the “shrinkage” of the hair will make it seem about 40% shorter than the straightened out length.

 to see our hair length guide to get an idea of the potential shrinkage when the hair is tightened. We also provide the stretched length which can be done with methods used to stretch your own hair (combing out, braid/twist outs or whatever your preferred method is!)

Our Bundles range from 100g to 140g and are double-drawn. This means that over 75% of the hairs in each set of Ruka extensions are true to the advertised length and more consistent in volume from top to bottom (unlike the industry-standard single-drawn extensions).

We recommend 2 bundles for a standard sew-in , but you may wish to use 3 depending on how full/voluminous your desired finish is. To create a wig, we recommend 3 bundles and a closure.

Our Clip-in sets range from 160 - 180g and 1 set ( always a minimum of 8 pieces ) is designed to cover a full head with a finger-width of leave out for a natural boost of volume . If you’re after a much fuller look, and especially if purchasing stretched textures in 18” and above, you may want to consider getting 2 sets. Please take a look at the 'Product Specs' listed on each product page for the specific weight of that item, as these will vary by length.
