Dying Hair Extensions Disclaimer.

Results may vary with different brands and types of hair extensions and dyes. We cannot be held responsible for any issues that may occur during or after the dying/toning process as the reaction and application methods may vary. To ensure desired results, it is recommended to test the dye/toner on a small piece of hair before fully committing to the process.

Dying/toning can be a drastic change as the chemicals involved can negatively affect the texture, quality, and longevity of the extensions. The product may experience increased dryness, shedding, tangling, and breakage. Our hair extensions undergo a rigorous dying and bleaching process to achieve their stunning shades.

Actual colours may vary. This is due to the fact that every computer monitor has a different capability to display colours and that everyone sees these colours differently. We try to edit our photos to show the samples as life-like as possible, but please understand the actual colour may vary slightly from your monitor. We cannot guarantee that the colour you see accurately portrays the true colour of the product.

Micro bonds are almost half the size of standard keratin glue beads.

Micro Keratin bonds tend to melt more easily compared to standard beads. This feature adds to the convenience of working with them, making them an attractive option for hair extension stylists.

Additionally, the bonds appear tidier and more polished, which can be a significant factor in showcasing your work as a stylist in your portfolio.

- The placement of the bonds allows your hair to move naturally.

-They offer more natural looking hair than taped-in or sew-in hair applications.

-Fewer maintenance appointments than with other types of hair extensions.

-Curl, dye, straighten, and style your extensions just as you would with your real hair.

These hair extensions naturally air dry with a gentle wave, but to achieve the initial straight style, they require heat styling at 200 degrees.

You can opt to dye your Human Hair extensions to achieve your desired shade. Our sets can be safely toned/dyed as Portia & Alexa Hair is a premium quality 100% Human Remy Hair . 

Like most human hair extensions, Portia & Alexa Hair should not be bleached or lightened. Our hair goes through a long dying process to achieve our gorgeous shades, therefore please do not attempt to bleach or lighten your extensions as this may cause damage, shedding and dryness to the hair.

Dying Hair Extensions Disclaimer.


All hair extensions & dyes are different. You cannot guarantee your product will produce the same results from brand to brand. We do not cover any costs nor take any responsibility for any issues you may encounter during or after the dying/toning process as we cannot be sure how your specific product reacts or the method in which it was applied. Always test your dye/toner one small piece of hair first to ensure it gives you the results you want.

Dying/toning is considered drastic modification of the product as these products contain quite harsh chemicals that may effect the feel, condition & lifespan of your set. It may increase the chance of dryness, shedding, tangling & breakage. Our hair goes through a long dying and bleaching process to get it to our fabulous shades.
