HairUrchins™ Q&A

Here are answers to frequently asked questions

Can I apply the HairUrchins™ fibers easily by myself?

You can easily apply HairUrchins™ fibers by yourself. With a hand mirror, check to make sure the thinning area is completely covered. Over time, you’ll learn how much to use on your hair. Soon, you’ll be able to do it without using a mirror. So why wait? Improve your hair and feel more confident. Give Hair Urchins Fiber a try today!

How long does it take to apply HairUrchins™ fibers?

The HairUrchins™ fibers can be applied in seconds. Simply sprinkle the fiber on the areas of the thinning hair where hair loss is most noticeable. However, HairUrchins™ Fiber only works on areas with some hair left, so avoid using it on completely bald areas.

Can I use hair gels?

You can use hair gel, but wait for it to dry before applying the HairUrchins™ fiber. Additionally, we do not recommend using hair gel as it may make the hairs stick together and decrease the amount of hair visible, which can make it harder for the HairUrchins™ fiber to adhere properly to individual hair strands.

Can I use mousse?

To achieve optimal results with HairUrchins™ fiber, it's best to avoid using mousse altogether. Mousse can cause the hairs to stick together, reducing the surface area available for the fibers to adhere properly. However, if you choose to use mousse, make sure it is completely dry before applying the HairUrchins™ fiber. Apply the mousse first, style your hair, and let it dry completely. Then, apply the HairUrchins™ fiber as directed.

How do I use HairUrchins™ fiber and other medications at the mean time?

If you are using Minoxidil or any topical treatment, apply it and wait for your scalp to dry completely before using the HairUrchins™ fiber. It is always recommended to consult your doctor if you have any specific questions.

Can I comb my hair after applying HairUrchins™ fiber?

For best results, style your hair before applying the HairUrchins™ fiber, but you can still comb it afterwards with a wide-toothed comb. You can also use your hand and fingers to pat your hairstyle into place.

Does HairUrchins™ fibers work for any hair type or any hairstyle?

It's the perfect product for all hair types. Whether you have straight, curly, or wavy hair, HairUrchins™ fibers will work for you. Just sprinkle the HairUrchins™ fibers onto your hair and simply comb it through your hair and style as usual and you're good to go!

Should I apply Hair HairUrchins™ fiber to wet or dry hair?

HairUrchins™ fiber uses static electricity to adhere to existing hair. For best results, make sure your hair is completely dry before applying the HairUrchins™ fiber, as they will become lumpy if applied to wet hair.
