Q: What is Dr. Hair USA hair fiber?

In short, Dr. Hair USA is confidence in a bottle. It gives you the look of that youthful, full head of hair that you were once proud & confident in, in seconds.

For the longest time, victims of hair loss, had few available choices on how to deal with this problem. Some people opt for hair grafting techniques, but these are expensive and not covered by insurance.

If the hair loss is gradual, some try to use of topical hair growth formulas like minoxidil. These products have proven helpful for some, but, unfortunately, only work as long as you continue to apply them.

Keratin Hair Fibers is a fast and reliable solution for bald spots and hair loss by instantly giving you the hair a fuller appearance.

The reason that Keratin Hair Fibers works is that it is made with natural-colored, vitamin-enriched fibers that have a negative electrical charge which allows them to naturally cling to the positive charge of hair.


  • When you sprinkle the hair fiber on the thinning area of your hair, the fibers automatically cling to your hair like millions of tiny magnets making each strand of hair instantly becomes thicker and fuller. Once the fibers adhere to your natural hair they stay in place until the next time you shampoo. Go about your day with confidence, hair fiber will leave you worry-free about those embarrassing thinning areas.
  •  It will neither irritate nor harm your skin or hair.
  • You will love the quick results of  hair fiber as they give you a natural, thicker looking head of hair that will last from day to night.

Hair building  fibers (or sometimes known as hair filler fibers) are a completely different approach to building thicker hair while immediately providing the illusion of the same. They are electrostatically charged fibers made from different materials. The higher quality ones are made of natural fibers.

You apply the fibers by sprinkling them over thinning areas of hair, tapping them down upon the scalp with your fingers. The fibers cling to the existing hair and scalp and can be “settled” with a light application of hair spray. The hair filler fibers bind to individual hair shafts, making each strand of hair appear thicker.

They will not brush out or blow off in the wind, but will provide a natural looking scalp cover and hair filler until your next shampoo, when they wash completely away.


Q: How Different is Dr. Hair USA?

Dr. Hair USA uses natural resinous gossypium herbaceum fibers and keratin. It contains no formaldehyde, ammonia based derivatives, or preservatives, so the fibers will not damage the hair, irritate the scalp, block the scalp pores, cause dandruff, or any kind of long/short term hair or scalp damage.

Dr. Hair USA has higher density & greater adsorption capability of static electricity, result shown as following:

Dr. Hair USA hair building fibers is lighter and thinner, with better dispensibility and stronger adsorption capability of static electricity. Result is greater capability to intertwine with hair to create better appearance of real human natal hair, as it bonds 80% more securely to existing hair. Notice the 100x microscopic view of the hair fibers as compared to our competitor brands.

Dr. Hair USA has greater color stability against fade. This experiment shows Dr. Hair fiber and competitors soaked in water for one week:


Q: Will Dr. Hair USA hair fiber work for me?

That’s a GREAT question – the most often asked, by the way.

Not everyone is a candidate for hair fibers. Here are some that are PERFECT for Dr. Hair USA hair fibers

Here’s a general rule: you need SOME hair on top of your head for Dr. Hair USA hair fibers to work.

Q: How do I apply hair fiber?

  • Make sure you dry your hair. Style as usual.
  • Shake Dr Hair USA onto your thinning areas, as if you were shaking grated cheese onto a bowl of pasta.
  • If necessary,  you can gently pat the applied area to disperse the product. If you want more natural look, feel free to skip this step.
  • To create more natural look, comb or brush your hair around the area where you applied Dr.Hair.
  • If you want more “sturdy” fiber, apply a bit of hair spray to lock down the fibers onto your hair

Make sure you have mirrors positioned in such a way that you can see the areas you are applying the fibers on.

Here’s a video from one of our regular customers (who also happens to be a doctor).


Q: How is Dr. Hair USA different from other brands?

Dr Hair USA uses natural herbaceum (cotton fiber), not chemically laced plastic based fibers.

Some hair fiber brands can cause scalp irritations.

Other brands are known to use ammonia and formaldehyde derivatives, which have been linked to cancer and other skin diseases.

Would you use, or even recommend to a friend, products that contain harmful chemical laced products?

Probably not.


(Reference our MSDS, Material Safety Data Sheet)

Dr. Hair USA hair fibers are made from Moroccan gossypium herbaceum, or regular cotton fiber.

100% organic, and never laced with known harmful chemicals.

In fact, even the electrostatisticity is far superior to the other brands, which gives the fibers greater “cling” without sacrificing the “voluminous” hair look.

Even its water & sweat resistance is much much superior to our low priced, low quality competitors.


Q: What if I don’t like the product?


Don’t like Dr. Hair USA?

Return it and we’ll refund your money, no questions asked.

(Refer to our refund policy page for full details)


Q: Does Dr. Hair USA come off in rain or if I sweat?

See the video here

Remember that is is hair fiber that attaches to your temporarily. So it will definitely come off lots of water (or sweat) is applied to it.

Unless you are in super heavy monsoon / thunderstorm where your scalp is directly facing in the direction of heavy water flow, Dr Hair USA hair fiber resists most light water flow.

We do not recommend that you use the hair fiber if you know that you’ll be in a situation where you are constantly sweating (like in gym, wearing a hat, or any condition that might cause sweat to collect & flow down your scalp).

Other than that, Dr Hair USA fiber will work in most social conditions


Q: How long does 1 bottle last?

It depends on how much use on daily basis, but for people with moderate thinning hair, it can last anywhere between 2 and 12 months.

Much shorter if you use more frequently, and less if you use sparingly.

Our customers have reported an average of 3-4 months.


Q: What colors are available for Dr.Hair USA?


We currently do not have other colors unfortunately. If you’d like us to carry new colors, please request which colors you want so that you can be notified when they are released.


Q: How long will it take to receive my bottle of Dr. Hair USA?

A: In US, we use standard US post office shipping. So it should take 2-4 business days.

In Asia, 1-2 days from day of order since we use Kerry Express so you can rest assure that you will receive the product as quickly as possible.

    Fills in well…stays put. I’ve tried others and this one is the winner. I will order again and recommend it

  3. Rebecca Hill DDS (verified owner)

    Works great

  4. Lisa Gregory (verified owner)

    Works surprisingly, but hard to apply evenly.

  5. Amy Howell (verified owner)

    its nice product not a bad one. hope these companies improve the fiber more in their future versions.Wish these companies come out with something that grows the natural hair too. 🙂

  6. Brandon Palmer (verified owner)

    I am SO glad I finally found something that covers up my slightly thinning hair. This stuff is exactly what I was looking for. It darkens my scalp so that it looks like my hair is continuous. I have the dark brown and light brown, and both look pretty good depending on how long my hair is. My only complaint is that sometimes it clumps up and may fall onto your shirt. If it does this, especially in sunlight people will start wondering what is in there. Also, be careful when you put it on….you can easily breathe in the particles. My lungs hurt the first day I had this and I finally figured out why.

  7. Tammy Jones (verified owner)

    I just bought the Auburn, size .42 today. And it actually matches my hair. I have been dying my hair dark brown to have a color that matches my other fibers/sprays. I’m pretty excited I can have my red back. I also bought the applicator which fits the bottle.

  8. D. Wilcox (verified owner)

    The good news is that it does what it’s supposed to do. I have very thinning hair on my crown, and use it to show less scalp. I am a single female, and as you can guess, this is devastating on both my personal and professional life. I recommend buying multiple colors and creating a cocktail that matches your hair color. I buy dark brown, medium brown and (just a touch of) auburn. I mix my specific recipe in a bowl and then add back to the container, with the spray nozzle (sold as accessory). Yes, I take this seriously! ha ha!I do not wash my hair every day because my routine requires a blow dryer and flat iron, which contributes to hair damage and fall out. (Oh, to be a woman!!!) So, I wash my hair only 2-3 times per week. By day 2-3, the Dr. Hair fibers need a refresh. Spraying more on top could look matted and globby on your scalp. Solution: My added routine requires cleaning my scalp of the fibers with a q-tip and sea breeze. Or, I will wash the front of my hair only. I believe that it’s good to allow your scalp to breathe, and not get clogged, so I will do the sea breeze routine at night before bed and massage my scalp (inversion method). Inversion method is to bend at the waist leaning forward, to increase blood flow to your scalp, while massaging.

    When I started thinning on top of my head I knew I needed to do something. I’m a female age 56 and I think Menopause was the reason for my thinning hair. Anyway, when anyone was talking to me they would always scroll with their eyes up to my head looking at the thin parts. I became very embarrassed, especially when the wind blew it was worse. Since using Dr. Hair I’v notice they do not look at my thinning head anymore. But, sometimes in the sun when the wind blows it’s a little more apparent.I will continue to use this product.

  10. Zachary Dixon (verified owner)

    Really gives the appearance having more hair. It blends in with the natural hair to cover thin and balding areas to make it look full. The fibers stick to the natural hair and washes out when the hair is washed. There is several colors to choose from which helps to find a shade that matches the natural hair. All you have to do is sprinkle the fibers on in the areas that it is needed, then spray hair to keep it in place. Wonderful product and I will be buying it again and recommending it to others.
