RevivHair Review: Can You Make Your Hair Grow Longer?

Wouldn’t it be nice if we could take a pill and have it quickly affect the length of our hair? If you spend anytime on Instagram you probably see thousands of people selling pills that promise to increase the length of your hair. There are before and after pictures showing several inches of growth over a short period of time, such as 4 to 6 weeks. Is this for real?  What about a topical product such as RevivHair Stimulating Serum that is applied to the scalp? Could that make your hair grow longer?   Let’s explore the reality behind hair growth to answer these questions.

What affects how your hair grows?

Hair growth is affected by the anagen phase of a hair follicle. The longer the anagen phase, the longer the hair will grow.  The length of this phase of hair growth is primarily determined by genetics  but hormones can also play a factor.  Like anything in our body, some chemical is released that tells the brain to begin or end the anagen growth phase.

When the anagen phase is over, the follicle enter the catagen phase. Scientists have not determined what the actual trigger is to enter this phase but during this period, hair doesn’t grow. There is no blood supply to the roots or cells that produce new hair.

Finally, the hair follicle goes into a resting state, known as the telogen phase. Essentially, the hair is now dead. Hair in the telogen phase falls out easily and sheds away when we comb and brush our hair. Eventually new hair beginning in the anagen phase will push the old hair out if it didn’t come out on it’s own.  This is referred to as the exogen phase and it’s normal to shed 50-100 hair per day that are in this phase.

Given this information, we can conclude a few things:

  • Different hair on your body has different lengths of time it spends in the growth phase. For example, if you never shaved your legs, the hair would not likely grow to 12 inches. We can conclude the anagen phase is shorter for that hair.
  •  Different people experience different lengths of time their hair spends in the anagen phase. For example, some people have longer hair on their arms than others. The longer arm hair was in the anagen phase for a longer period of time.
  • People who cannot grow hair more than a couple of inches do not have a long anagen phase. In some rare exceptions where you see hair that as grown to a person’s knees, you can conclude the person has an exceptionally long growth phase.

How long is the typical anagen phase?

The length of time hair spends in the anagen phase varies for people.  The average time is 2 – 6 years.  For your arms and legs, the average time is about 30 days.   Not all the hair follicles are in the same phase at the same time.  About  85%-90% of your hair is in the anagen phase, 1-2% is in the catagen phase, and 10-14% is in the telogen phase.

If your anagen phase is 5 years and another person’s  is 3 years, the maximum length each individuals hair can grow will be different.  The key to growing your hair longer than the maximum predetermined length would be to extend the  anagen phase.  This would have to be ongoing, otherwise, once the anagen phase concludes and the longer hair is naturally replaced, the genetic or hormonal controls that determine the time your hair spends in the growth phase will revert back to what it has always been.   This is kind of tricky when you are thinking about how to grow your hair longer than it is predetermined to be!  If there is a successful extension of the anagen phase, it has to be sustained for new hairs that restart the cycle to maintain the longer length.

RevivHair Review – Can this serum make your hair grow longer?

RevivHair Serum

If it can extend the anagen phase, then the answer is yes.  What does Reviv Serums say about the science behind their product?

The key product in RevivHair is Redensyl® 3% from Induchem.   This product combines two patented Induchem molecules – DHQG and EGCG2 – to help hair loss and the reactivation of hair growth by targeting hair follicle stems cells, reactivating the proliferation of ORSc stem cells, protecting them from apoptosis, maintaining their differentiation properties and helping to activate the metabolism of dermal papillary fibroblasts.

I realize that’s a lot to take in and I wasn’t quite sure how to summarize it into simple terms.  Take a look at this video which will quickly visualize what the product intends to do.  Also,  Reviv Serums website has all the key ingredients listed out with details on what they are proven to do.  Redensyl® is swiss based technology appearing in the U.S. for the first time in this new serum.   There are many more active ingredients including stem cells, growth factors, peptides, and natural extracts that are also included in the serum.  I would encourage you to look at the extensive science that has been considered and applied to bring this product to market.

One of the things I rely on the most are real clinical trials.  Some companies don’t publish results but Reviv Serums has offered to share theirs and results were positive.

Induchem’s clinical assessment on volunteers produced outstanding results for Redensyl. In less than 3 months, 85% of the volunteers had significant and visible success, with +9% of new growing hair and -17% of falling hair. 85% of subjects showed positive results.

For people with long, thick, full hair it’s not as easy to determine if the growth cycle was extended.   If the hair has reached what you know to be the longest point, that hair has likely entered the phases following the growth phase and only the new growing would be in the anagen phase and potentially growing longer.  So, for me, I can’t determine if that phase is going to last longer and I will get an inch or two of additional growth.  I would need to see if the new hair extends beyond where my hair would normally grow to and that takes time to assess.  My hair has reached it’s maximum length.   For people with thinning hair, an immediate benefit may be noticed because hair may quickly stop shedding if it stays alive longer remaining in the growth phase.

My experience using RevivHair Stimulating Serum

For a period of 7 weeks, I applied Reviv to my hair nightly and I continue to do so,  The product can be used on wet or dry hair.  I applied it while my hair was dry.  The application is easy.  The bottle has a dropper and one dropper full is what I applied and massaged into my scalp each night.

The serum is light weight, nearly odorless (some people may not be able to detect any scent but there is a  very mild medicinal scent) and it dries quickly.  The product is not sticky and leaves no residue or flakes.  Once it dries, there is no smell and it is undetectable in my hair.  It didn’t even leave a sticky feeling behind on my hands.  I loved this about the product.  I did not experience any irritation or itching and most important, there was no undesirable change in the texture or sheen of my hair.

As you may recall from previous experience with other company’s hair growth accelerators, I experienced what appeared to be loss of shine, dry, coarse hair, and undesirable texture.  This did not occur with the Reviv product and I intend to continue using it to determine if my hair can grow longer than it’s current maximum length.  My choice to continue is based on my belief that the product will work and it’s been meticulously manufactured.  Since the anagen phase can last anywhere from  2 – 6 years (some sources state 7), I won’t know if my newer hairs grow longer until further in the future.

RevivHair Review Conclusion

With reliable scientific evidence and a reputable product, it is very possible you can get your hair to grow longer than it’s predetermined maximum length or prevent hair from thinning.   With an understanding of how your hair moves through different phases, it should be apparent nothing is going to give you 4-6 inches of growth in 8 weeks (sorry).  The hair won’t grow that fast and it would take more time to determine if the hair passes the longest point it was ever able to reach unless your anagen phase was extremely short and that’s uncommon.

If your hair is currently in the anagen phase, nothing is going to make it shoot out of your head so fast that in 8 weeks, it will be 4 inches longer.  Only extensions will produce that and I’d bet that is what you are seeing in Instagram photos!  In order to affect the life of the cells and the length of time your hair remains in the anagen phase is going to require expert scientists and extraordinary formulations.   So, to answer the original question.  Would a scientifically proven product, such as RevivHair,  given the necessary time to assess based on how our hair growth cycles create longer hair?  Yes, it is possible.  Will the pills you for sale everywhere give you a luscious mane in 2 months?  I think you can now answer that for yourself.

    1. I know. Same here! The growth cycle is only so long so once the hairs enter the dormant phase. They don’t start growing again. We shed them so we really do have a max length our hair can grow too. And mine is not exactly what I consider a bonus feature!! Lol

        1. Just depends on how long the growth phase is for the hair. One person may be 2 years and another may be 5 and the latter is going to be able to grow much longer hair. Mother nature is not fair!!

  1. More than I ever needed to know about hair growth! 😀 I am still experiencing post partum hair loss, so I’ve done a bit of research into it, too, just so I have an idea about what’s going on. It sucks! Aarrrrgh.
