The MK 677 Hair Growth Protocol: My Experience With using Ibutamoren to Regrow Hair

MK 677, also know as ibutamoren, is a growth hormone secretagogue used by fitness enthusiasts as an alternative to HGH. Bodybuilders use it to stimulate appetite and gain muscle, but its uses extend far beyond that.

MK 677 improves sleep quality, shortens recovery times, and jump starts collagen production. Collagen is essential for healthy hair, clear skin, and strong nails.

This article will show you how to use MK 677 to grow your hair. I’ll explain what types of hair loss you can treat with it and what dosage to use. If you haven’t already, make sure you read our full MK 677 writeup as well.

Is It possible to grow hair with MK 677?

MK 677 Hair Growth

Since MK 677 is a somewhat newer drug, there haven’t been any studies done that specifically look at whether or not it can regrow hair. With that being said, we can make a few reasonable assumptions by looking at the science.

First, we know for a fact that 20mg per day of MK 677 increases serum IGF-1 levels by more than 50% and nearly doubles HGH production:

MK 677 increases serum IGF-1 levels.

Second, we know that IGF-1 plays a big role in hair growth in humans. According to this study, IGF-1 stimulates hair growth in a dose dependant manner. 

Finally, we know that high levels of growth hormone in the body are associated with increased collagen production. Collagen is essential for hair growth, as explained by this article from Healthline.

My experience with taking MK 677 for hair growth

My Experience

I’ve been taking MK 677 for the better part of 3 years (with occasional breaks). It’s one of my favorite compounds because it’s one of the only things I can take for extended periods of time without diminishing returns.

My hair used to be very inconsistent; sometimes dry and flaky, sometimes super oily to the point where I’d get terrible scalp itching. I tried a handful of different at over the counter treatments including Nizoral, coal tar, hydrocortisone, and a list of others.

On top of that, I was beginning to thin on the top of my head.

MK 677 fixed nearly all of it. I still get the occasional dandruff, but nowhere near the level as before. The best part is that my hair looks noticeably thicker and healthier.

By no means was I bald before, but looking at pictures from before and after I started shows a pretty clear difference. My hairline didn’t change, but my actual hair is way thicker than before.

It looks like I’m not the only one who has gotten good results with using ibutamoren to regrow their hair. This post from the Tressless hair loss subreddit shows someone who got similar results:

The MK 677 hair growth protocol


The MK 677 hair growth protocol is simple: 25mg a day for 12 weeks, followed by 4 weeks off.

I’ve found that this cycle works best and keeps my body from getting desensitized by the effects of having increased growth hormone and igf levels. 

You might need to adjust things to suit your needs, and some people see good results with a much smaller dose of 10mg. See how your hair looks after a few weeks on 10mg and if you want to try a larger dosage you can.

Remember, growing hair is a marathon, not a sprint. It’s a long term goal and you’re not going to see overnight results with hair loss remedies. This is true even for prescriptions such as finasteride and dutasteride. 

I’d recommend committing to 12 weeks to start. It’s really not worth the time or the money to use it if you’re not going to allow it enough time to do it’s job. 

Combining MK 677 with Finasteride and Minoxidil

Ultimate Protocol

Growth hormone secretagogues such as MK 677 are fantastic tools to improve your health and appearance. With that being said, there are many other avenues to explore if you are beginning to lose your hair.

The one’s that are clinically proven to be effective include what many refer to as “the big three”:

  1. Finasteride, a prescription drug used to slow and reverse hair loss.
  2. Minoxidil, also known as Rogaine. Topical solution applied directly on the scalp.
  3. Ketoconzonole shampoo. Sold under the brand name Nizoral and many generics. Available over the counter.

I recommend checking out the Tressless subreddit for more information regarding those treatments.

Final Thoughts

At the end of the day, HGH and IGF-1 are vital keys to hacking the aging process. It’s a staple in my lineup and I recommend to anyone interested in using it for hair growth/regrowth.

Does MK 677 cause hair loss?

No it does not. There is no evidence that suggests that it can cause hair to fall out or increase the speed of balding. On the contrary, there is multiple cases that support using it to strengthen and grow hair!

When should I take MK 677?

If you’re only using it to grow hair, there is no difference between taking it at morning vs taking it at night.

What is the correct dosage for regrowing hair?

Start with 10 to 15mg a day for 12 weeks. You can always increase the dose later as needed, but it’s best to start low and find the minimum effective dosage before increasing it.
