SureThik® is currently available in Black, Dark Brown, Medium Brown, Light Brown, Sandy Blonde, Light Blonde, Auburn, and Grey.

The best results are achieved by matching your exact shade, or a shade that is slightly darker than your natural hair color.

No, SureThik® is an all-natural product. The ingredients contained in SureThik® are as follows: Keratin, Silica (less than 1% and various colors to create shading.) SureThik® fibers are 99% Natural Keratin.

Since SureThik® is an all-natural complex of organic protein. It is completely safe to use with topical hair loss treatments such as Minoxidil®. Just use your favorite topical treatment, allow your hair to dry and apply SureThik® for a great looking head of hair every time.

SureThik® is recommended by many hair transplant surgeons to their clients because it is completely safe and it works extremely well on hair transplants. Even if you’ve just had hair transplant surgery, SureThik® will completely eliminate the appearance of any temporary post operative thinning, scabs, or scars.

No, SureThik® is an all-natural product. It does not contain any active ingredients than can possibly interact with or irritate the scalp.

Yes, you can leave SureThik® in your hair overnight. You may find a few stray fibers on your pillow case the following morning. We suggest using a darker color pillow case and the small number of stray fibers will not be noticeable at all. Another tip is to try and shake any loose fibers in your sink before bed time if you use a lot of fibers.

No, once you have brushed SureThik® in it will be completely undetectable. Even from 2 inches away, it is extremely difficult to notice. We’ve had clients who reported going to the barber with SureThik in their hair and have not had their barber notice anything unusual at all.

Because of its micro composition, once applied, the SureThik® fibers bond to your own “Vellus” and thinning hair so securely that even strong blowing wind or heavy rain will not cause it to run, stain or smear, yet it washes out easily with practically any shampoo.

SureThik® works very well on diffuse thinning and on thinning patterns in the Norwood scale which range from 1-5.
