hair extension length guide
Not sure which length to choose?
Choosing the right length can make all the difference. Our hair extension length guide helps you visualize how each length will look, so you can confidently select the perfect option to match your desired style and overall look.
Frequently Asked Questions
How many bundles do I need for a full sew-in?
Density is always based on personal preference. For standard volume guidelines, we recommend 2 bundles (200g) for lengths 16" and above. For lengths 18" or more, we recommend 3 bundles (300g) at minimum.
Can my extensions be hot tool styled?
Absolutely! When working with luxury human hair extensions, you can (and should!!) treat them just as your own hair growing from your scalp. Before using any heat tool (straightener, curler, blow dryer, etc), we highly recommend applying a heat protectant.
Will the curls revert after washing?
Yes! Your curly extensions will go back to their curly state after washing them. We highly recommend allowing the extensions to air dry after detangling them thoroughly.
Is the hair ethically sourced?
Yes! All Sleek by Hailey extensions are made with 100% ethically sourced cuticle-aligned human hair from donors.
Can I dye or bleach this hair?
Yes! We highly recommend that a professional perform any coloring to keep the hair in its best condition.
