  • Toppik Hair Fibers. XFusion Toppik hair fibers are constructed of the very best keratin. The fibers match the natural keratin found in human hair. Keratin fibers create a natural static charge. This “electricity” adheres to the keratin in the hair follicle. The technology behind Toppik keratin fibers is easy!

Toppik has also formulated the fibers to stay wind, sweat and rain resistant.  XFusion Toppik Hair Fiber application is guaranteed to be easy and long-lasting. Whether traveling or adding Toppik to the daily routine, XFusion Keratin Hair Fibers are available in 4 sizes between 3 and 55 grams. Thinning hair has found a friend.

How Toppix is Applied

Application of XFusion Toppik hair fibers is easy. Remove the cap from the keratin fiber container. Next, face the mirror and shake the keratin fibers in the thinning places on the scalp. No combing or heavy patting like competitive products. Finish with Toppik Fiber Hold Spray. This second step is literally fast and fuss free. Apply the Hold Spray to the places the fibers were applied! There’s no big time commitment. Figuring a way to work this application into a morning routine is a breeze. Toppik products come in travel sizes too, making for easy on-the-go applications late in the day, or for date night. Hair stays looking thick and healthy.

For a more refined look, and for treating thinning hair, Toppik offers affordable options. For a complete XFusion Toppik Hair Fiber experience, or one of their other fiber-enriched products, consider the Perfecting Tool Kit which includes two add-ons.

    • Hair Fiber Optimizer. Optimizing starts with a comb. The Hair Fiber Optimizer is a rounded comb that fits in the palm. It’s unique design uses sporadically placed, uneven teeth. This allows the hair to naturally fall into place and not create any false hairlines, or parts. With perfectly combed rows, less keratin hair fibers will fall onto the forehead and bathroom sink during application.
    • Toppik Spray Fiber Applicator. This patented applicator fits on the regular and economy size Keratin Hair Fiber bottles. It works like a pump, using air and its unique beak-style nozzle. This special nozzle allows for precision application. This ensures even coverage on the hair and scalp. It also works great as a root blender, and for covering up connector points and tie-offs if you wear hair extensions.

Keratin Hair Fibers – The Basics

XFusion by Toppik, Keratin Hair Fibers: Full Review

The effectiveness of keratin fibers, and how they deliver good results is key to a natural look. It’s about how they adhere to the hair follicle. For these reasons, it’s important to consider the cost. How much surface area needs to be covered, and how often? The largest bottle will last about 3 months.

Also, consider fiber retention between washes. How long do the fibers adhere to the hair follicle? Although keratin fibers won’t shed on pillow and clothing, daily use requires daily cleansing. Toppik recommends using keratin-rich shampoos. Keeping the scalp clean and healthy is very important. It aides in the prevention of side effects. Several shampoo options are available on the Toppik website.

Side Effects?

Side effects may occur from the use of keratin fiber hair thickeners. Most noteworthy are redness, irritation, itching and severe skin reactions. Consider the side effects when starting any topical application. The combination of rubbing and combing can cause the fibers to seep into the scalp. They can then embed themselves under the dermis layers. This can cause burns, which may require medical treatment and steroid creams. Talk with a dermatologist or your primary care physician. Remember, keratin fiber applications are a temporary fix, not a scalp treatment.


  • Easy to apply and stays on all day (no fall or spreading).
  • Looks completely natural.
  • You can style your hair and use other products with no issue. 


  • Some complain that it is too powdery.

Christopher is the founder of Hair Loss Geeks, which launched back in 2011. At the time there wasn't any credible information on the internet about hair loss. As someone suffering from hair loss himself, Christopher began his extensive research journey. After launching the site, he later graduated from Boston University in 2012 with his PhD in Biochemistry. What started off as a hobby project quickly became a bigger focus as it grew. Christopher hopes everyone can learn from both his experience and research.
