Keratin MD is a supplement that promises it will give you longer, thicker hair in 21 days, or your money back. They state Keratin MD is the product of years of research and is a breakthrough formula that transforms ordinary hair into the locks of a runway model in a very short period of time.

Why is my hair so THIN?

Female pattern hair loss (known as adrogenetic alopecia) is a lot more common that you probably think, affecting 30 million women. Although it primarily occurs in your 50s or 60s, it can appear in teenagers as well. This is understandably frustrating, embarrassing, and depressing for many women that want to have looks like the models in magazines, and unfortunately like its male counterpart, there is no cure.

Still, there may be other reasons other than genes why you are experiencing thin hair or excessive hair loss. Are you dyeing, crimping, blow-drying, or otherwise abusing your hair? What medications are you taking? Are you pregnant, or on the other end of the spectrum, going through menopause? What’s your level of stress? In other words, there could be a number of other factors causing thin or brittle hair. If you are experiencing sudden hair loss, you should see your doctor.

What’s in Keratin MD that they say makes it so great for my hair?

Keratin MD doesn’t specifically list the ingredients except to say that it contains “clinically proven stimulation ingredients such as enzymes, peptides, antioxidants, and key vitamins” and on one of their websites they point to 4 different clinical studies that they claim back them up.

It turns out we’ve seen these exact same studies used for another hair growth supplement called Keralox, although there is no indication the two companies are related. (Keratin MD also appears to have no relation to KeratinMD, a topical concealer for balding men.)

But let’s take a look at these studies, and see if they do offer any proof that the ingredients in Keratin MD will actually work.

Study 1 is a pilot study using niacin derivatives to treat female alopecia. Although they state that the people who used niacin derivatives showed a statistically significant increase vs. a placebo, we’d like to point out that the niacin was applied directly to the scalp, while Keratin MD is a pill you take by mouth. (It also was a preliminary study and not a full-scale trial.)

Study 2 actually contradicts what Keratin MD is saying because it states “Excessive intakes of nutritional supplements may actually cause hair loss and are not recommended in the absence of a proven deficiency.”

Study 3 is not really a study at all but a link to the University of Maryland Medical Center page on Vitamin H (biotin) which states there is “very weak evidence” that biotin helps with thin hair or brittle nails.

On first glance, Study 4 seems to be the most promising proof yet, because it claims to be a double-blind placebo controlled study evaluating the effectiveness of taking an oral supplement to thicken hair. However, the study is evaluating self-perceived thinning hair and states that the mean number of hairs in both the placebo and the treated subjects “did not significantly change.” What did change is the women’s perception of their own hair, meaning they were experiencing the placebo effect.

Conclusions: Keratin MD’s own evidence does not appear to back up their claims that taking their supplement will help grow thicker, fuller hair.

How they get you to try Keratin MD for “free”

Keratin MD uses a similar tactic many of these hair-thickening supplements use by dangling a “trial offer”. They claim for just a $4.95 shipping fee, they’ll send you a 30-day supply for you to try and if you don’t like it you can return no questions asked. BUT:

  • The trial period lasts just 10 days from date of order, not when you receive Keratin MD. Since shipping times on these products are never guaranteed (and often purposely delayed) this can mean a very short window to cancel.
  • We’d also like to point out that they state it takes 21 days for Keratin MD to work.
  • After this 10-day window, you will be billed $87.47 for the bottle they sent you and signed up for automatic shipments every 30 days (where you are billed $87.47 each time).
  • If you check the box below the Terms & Conditions agreement, you will also be enrolled in something called The Best Fit Club for $1.99 per month until you cancel.
  • Even filling out the form for the trial offer gives Keratin MD the right to “use the personal information that you supply to us to bring selected retail opportunities to you via direct mail, email, online and telemarketing.” (So even if you decide not to order, they can still solicit you.)
  • You are also agreeing to not sue them or join any class action lawsuits.
  • Open items are non-refundable.

Bottom Line: Is Keratin MD a good way to get thicker, longer, sexier hair?

Simply put, Keratin MD does not disclose what’s in their supplement, nor do they supply any evidence that it works. Aside from the glowing testimonials on their website, we could find no reviews of their hair supplement.

And, as we’ve shown, it will be very difficult to avoid paying at least $87.47 for the first bottle.

While they don’t seem to be affiliated with any other “grow hair fast” supplements, we’ve seen this type of sales pitch before with TLS Hair, Silk Advanced Biotin Formula, and Silk of Morocco. All of these companies use short trial periods and hidden auto-ship programs that many consumers call “scams”. Therefore, we suggest avoiding Keratin MD.

What to do if you have thinning hair?

If you’d like to have longer, shinier, fuller hair naturally we suggest:

  • Eating more almonds, walnuts, flaxseed, or salmon for fatty acids
  • Bananas, potatoes, and spinach for more B3
  • Tomatoes and citrus for folic acid
  • Chicken, eggs, and soy for protein
