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.

    I am post transplant I was hoping this would help during the ugly duckling phase. This was grey. I ordered brown to see if that is better. I will update when I get it. So far not impressed.Update…getting the right color helps. I have lots of baby hairs that are starting this product finds them and makes hair look full. It takes a couple times to get the technique down for applying it. I found the applicator works best. Keep it moving kinda like spraying paint. You will get dark spots if you stay in one place. It works better the more hair you have. I am confident enough to go without a hat in public. You have to be careful not to touch once you have on. It comes off. I definitely would not sleep with this because it will come off. Not sure yet what happens if you start to sweat. You will not be able to fool your partner with this so I would try.

  2. Steven Jackson (verified owner)

    I bought this for my husband and he loves it, he just puts in on the bald spot and then some hair spray and he’s good to go.You can definitely see the difference.I didn’t give it a 5 because it is a little messy since you have to put it on like baby powder so I have to clean the sink every time he does it and also when he washes his hair.But other than that, I think its worth it and much cheaper than having implants.

  3. Joshua Barr (verified owner)

    I bought this in trial size just in case I didn’t like it, but I’ve been really happy with it overall. I have light brown hair and the color matched just fine. Application is easy, I roll up a washcloth and place along my hairline when I’m applying. I use a comb to gently blend. I have two areas where my hair has become so thin that my scalp shows through. This stuff totally hides it. Seems to last the day and I haven’t had any issues with it changing color with hairspray. I would try this in the sample size if you’re unsure about it. Only 7 bucks so not bad. I gave 4 stars only bc if you have a receding hairline its tough to get a good natural looking line right in the front.

  4. Beth Cortez (verified owner)

    I’ve been using the Med Brown color with great success, but its slightly darker than my hair so I tried the Light Brown. The Light Brown color is a closer match, but it also gives off a very faint green-ish look. It’s nothing too bad, it’s not like some lime green punk rock hair dye, but it definitely does show a green tint. I didn’t notice at first, then after I’d left the house and was driving I looked in the rearview and had to do a double take. Yep, definitely a green tint. I’ll stick with the Medium Brown as its close enough and doesn’t have any green tint to it. That said, this product is amazing. It really is. Wind, rain, you name it, nothing messes with it.

  5. George Smith (verified owner)

    I’ve used this before and it works really well.

  6. Miss Lisa Rodriguez DVM (verified owner)

    Works very well and easy to apply. Looks natural – almost completely undetectable unless someone were to get a magnifying glass and really inspect your scalp. The only downside is that if you don’t wash it out before you go to bed it’ll fall out onto your pillows, so if you’re a morning showerer then it’s trouble (although this can be easily washed out).

  7. Phyllis Zimmerman (verified owner)

    My wife’s lovely silken black hair began the hereditary thinning about a decade back and progressed to the point of showing wide gaps of scalp at the parts on the top of her head. This product has been a blessing through the past couple of years. She can apply it to the most needed areas and fix it with hairspray and no one will notice. We share this product as a gift to her mother also.

  8. Danielle Miller (verified owner)

    I have tried a number of different hair building fibers over the years, but Dr. Hair has a consistently good product. The dark brown color is quite close to my own hair’s color so it looks the most natural compared to other brands.My only complaint is that the fibers seem to clump a bit when first applied, making reapplication necessary in certain areas. Also, once applied, the hair cannot be rewetted or the fibers wash off. So, if you go swimming keep in mind that people will most likely notice that your hair is thinner than originally thought.UPDATE 07/04/20019:It took me some time to learn how to properly apply Dr. Hair without over-applying it, which can lead to blotching and uneven spotting on the scalp. I recommend that you use the spray applicator in order to get even coverage with minimal clumping and that you finish with a hairspray to hold the fibers in place.

  10. Kristine Valencia (verified owner)

    I gave mostly all four stars out of respect to the brand but I have not tried it yet, I have no clue how to use it, it is about the size of a battery so small so I gave it just one star for value and I will bring it to my HAIR SALON to ask the stylist how to use it!
