peppermint oil

By Chin­we of Hair and Health

The use of pep­per­mint oil for hair growth is not new at all to the nat­ur­al hair com­mu­ni­ty. Search the archives of hair care forums and blogs, and you will find at least one thread or arti­cle devot­ed to it. Nonethe­less, there has not been a con­crete study on pep­per­mint oil for hair growth … until now.

1. Let’s talk about pre­vi­ous research of pep­per­mint oil

Over the years, the ben­e­fits of pep­per­mint oil have been evi­denced in oth­er regards.

“… pep­per­mint has been report­ed to show anti-inflam­ma­to­ry, antimi­cro­bial, and anti­fun­gal activ­i­ties as well as strong antiox­i­dant activ­i­ty, and antial­ler­genic and anti­tu­mor actions. Sev­er­al clin­i­cal tri­als exam­in­ing the effects of pep­per­mint oil (PEO) on irri­ta­ble bow­el syn­drome have been report­ed. How­ev­er, exper­i­men­tal tri­al of PEO in its hair growth activ­i­ty has not been ful­ly report­ed.

In Decem­ber 2014, a thor­ough study on the growth ben­e­fits of pep­per­mint oil was final­ly pub­lished.

2. The study: method­ol­o­gy and exper­i­ment

“The aim of this study was to address the ther­a­peu­tic poten­tial of pep­per­mint oil (PEO) for hair loss via the com­par­a­tive analy­sis between PEO and minox­i­dil.”

Some of us are already famil­iar with minox­i­dil for hair growth, whether first-hand or through hear­ing the expe­ri­ences of oth­ers. Research also sup­ports this use and doc­tors wide­ly rec­om­mend top­i­cal minox­i­dil (Rogaine®) to treat some forms of alope­cia.

This par­tic­u­lar study was aimed at ana­lyz­ing the effec­tive­ness of pep­per­mint oil ver­sus the wide­ly used and researched treat­ment for hair loss, minox­i­dil. For the exper­i­ment, 100% pure pep­per­mint essen­tial oil was dilut­ed in jojo­ba oil (a car­ri­er oil). The mix­ture was then applied top­i­cal­ly once a day, six days a week, for approx­i­mate­ly a month.

The exper­i­men­tal design was as fol­lows:

“This study inves­ti­gat­ed the effect of pep­per­mint oil on hair growth in C57BL/6 mice. The ani­mals were ran­dom­ized into 4 groups based on dif­fer­ent top­i­cal appli­ca­tions: saline (SA), jojo­ba oil (JO), 3% minox­i­dil (MXD), and 3% pep­per­mint oil (PEO). The hair growth effects of the 4-week top­i­cal appli­ca­tions were eval­u­at­ed in terms of hair growth, his­to­log­i­cal analy­sis, enzy­mat­ic activ­i­ty of alka­line phos­phatase (ALP), and gene expres­sion of insulin-like growth fac­tor-1 (IGF-1), known bio-mark­ers for the enhanced hair growth.”

3. The find­ings

The results of the study showed that pep­per­mint oil had the most pro­nounced effect on hair growth com­pared to the oth­er three com­pounds. Addi­tion­al­ly, the oil showed sig­nif­i­cant increas­es in fol­li­cle count, or hair den­si­ty. Here is a snap­shot of the results:

- “At week 4, PEO showed hair growth at about 92%, where­as MXD about 55%

- “The depth, size, and num­ber of hair fol­li­cles were also marked­ly increased in PEO treat­ed skin.”

- “PEO showed remark­ably increased IGF-1 mRNA expres­sion at week 2, where­as MXD at week 4.” (NOTE: IGF-1 sup­ports cell growth and sur­vival while also play­ing a role to increase hair thick­ness.)

4. So what does this mean?

For those of you who use pep­per­mint oil for hair regrowth, you might actu­al­ly be onto some­thing!

“In con­clu­sion, our exper­i­men­tal data sug­gest that 3% PEO facil­i­tates hair growth by pro­mot­ing the con­ser­va­tion of vas­cu­lar­iza­tion of hair der­mal papil­la, which may con­tribute to the induc­tion of ear­ly ana­gen stage. In addi­tion, PEO effec­tive­ly stim­u­lat­ed hair growth in an ani­mal mod­el via sev­er­al mech­a­nisms and thus could be used as a ther­a­peu­tic or pre­ven­tive alter­na­tive med­i­cine for hair loss in humans.”

I was mas­sag­ing pep­per­mint oil and jojo­ba oil onto my scalp (and adding PEO to my sham­poo & con­di­tion­er) for about 8 weeks (incon­sis­tent­ly) but I end­ed up los­ing a lot of hair in the area that appears to be female pat­tern bald­ness (top of crown) so I got ner­vous and stopped. On the flip side I had some growth at the hair­line. I have been tak­ing black cur­rant seed oil (also stud­ied for hair regrowth poten­tial) since Sep­tem­ber and I think it has helped the growth. Any­one have the same expe­ri­ence with pep­per­mint oil? Thank you in advance fo… Read more »

Can pep­per­mint oil also be mixed with coconut oil, if so how much of each and how often can this mix­ture be used?

Also does mix­ture need to be rise out, or can this mitre be apart of my all nature process.


Take 3 mil­li­liters of 100% pure PEO (pep­per­mint oil) and mix it with 97 mil­li­liters of jojo­ba oil (buy it from Desert Whale® if you want obtain the “exact-just-the-same” solu­tion used in the study… not nec­es­sary).
Now you have a 3% pep­per­mint oil solu­tion (same con­cen­tra­tion used in the lab tests); rub it on your scalp and let it absorb the stuff; about 4 hours, like minox­i­dil; then you can sham­poo your head.
Use a syringe to dilute the oils with pre­ci­sion.


Put 3 mil­li­liters of pure pep­per­mint oil in 97 mil­li­liters of jojo­ba oil. Now you have the same solu­tion used in the sci­en­tif­ic study.
Rub it on your scalp and leave it there for the amount of time need­ed for its absorp­tion, not men­tioned by the study; let’s give it 4 hours, which is pret­ty fair for human scalp skin, the same for minox­i­dil.


[…] I still plan to wash my hair with the Ter­ressen­tials hair wash (sul­try spice ;)) while deep con­di­tion­ing with some Shea Mois­ture prod­uct. I’ve been mix­ing the Shea Mois­ture Deep Treat­ment Masque and the Dan­druff Con­trol Masque. I also add in a few drops of pep­per­mint oil for the tingly sen­sa­tion and the growth ben­e­fits.

Hahah..that was my next ques­tion!

I have a prob­lem with exper­i­ments being done on rats.….so wrong. Poor ani­mals

What’s the alter­na­tive? Exper­i­ments on humans? What if the peo­ple are unwill­ing? Should be hold back decades of sci­ence? How will we con­trol for all the genet­i­cal and lifestyle vari­a­tions in each per­son (remem­ber mice are all iden­ti­cal twins)? How will we afford this (to pay the peo­ple)? How will be pos­si­bly obtain a suf­fi­cient­ly large sam­ple size in order to pro­duce results that are sta­tis­ti­cal­ly sig­nif­i­cant? I am all for peo­ple hav­ing opin­ions. But if you do not pro­vide a viable alter­na­tive (and no, hold­ing back decades of sci­ence is not one), well… you opin­ion is just that– an… Read more »

…as opposed to exper­i­ments being car­ried out on humans? Should we instead vol­un­teer our prison pop­u­la­tion?

Rough­ly, PEO encour­ages the preser­va­tion of the old and new blood ves­sels that nour­ish hair fol­li­cles.


Ahh. Thank you so much.


Trans­la­tion: A fol­li­cle in its growth phase has a high­ly devel­oped net­work of blood ves­sels. Pep­per­mint oil pro­motes this net­work, thus forc­ing hair from its rest­ing phase to its growth phase.


Makes the ker­nel under­stand­able, but you’re let­ting pass an inex­act idea.
Hav­ing an active and devel­oped vas­cu­lar­iza­tion around a fol­li­cle, doesn’t mean that fol­li­cle is in, nor is induced to enter, an ana­gen phase; it means instead, that the fol­li­cle, either in ana­gen, cata­gen or tel­o­gen, will keep its vital­i­ty and will be pro­tect­ed against that phe­nom­e­non known as minia­tur­iza­tion which leads to alope­cia, AKA hair loss.
It also means that for fol­li­cles induced in a progressive/perennial rest­ing state by alope­cia, will eas­i­er re-enter in their phys­i­o­log­i­cal and cicli­cal ana­gen state, if it’s the case.


“by pro­mot­ing the con­ser­va­tion of vas­cu­lar­iza­tion of hair der­mal papil­la, which may con­tribute to the induc­tion of ear­ly ana­gen stage”

Can you trans­late this in laymen’s terms, please?


Right on time ! I pur­chased a bot­tle of pep­per­mint oil this week out of curios­i­ty! How do you use it? In your sham­poo, in your pre­poo?

La Shauna Grace

You can add it to all of your hair prod­ucts but if you put it in an appli­ca­tor bot­tle hop­ing to mas­sage your scalp make sure you add car­ri­er oils such as cas­tor oil, jojo­ba oil or olive oil. you can­not add it top­i­cal­ly to your scalp,for it is too potent and will burn your scalp.


Thanks for the info :)
