inositol for hair loss and hair growth

What is inositol?

Inositol, also known as myo-inositol, is a group of molecules responsible for signaling cells in the body.

While inositol is often referred to as myo-inositol, myo-inositol is actually one of the 9 inositol members in the most abundant form. This explains why most dietary supplements seen in the market use myo-inositol.

Here are 9 forms of inositol (Also known as stereoisomers):

  • Myo-inositol (The most commonly used inositol on dietary supplements as well as for PCOS symptoms)
  • Scyllo- inositol
  • Muco-inositol
  • D-Chiro inositol (DCI)
  • L-Chiro inositol (LCI)
  • Neo- inositol
  • Allo- inositol
  • Epi- inositol
  • Cis- inositol

One interesting fact shows that inositol is actually not a Vitamin B8 (common misconception), but it’s rather a sugar alcohol with a vitamin-like compound equally important in our body.

Inositol for hair loss – Will it give me new hair growth?

We found some interesting research studies as well as a real life example on how inositol can help with androgenetic alopecia – aka general diffused-thinning hair loss.

Research finding

Using inositol as a natural substance to decrease excessive testosterone: A number of studies (examples here and here) show that women with polycystic ovary syndrome (PCOS) often show symptoms of hyperandrogenism – excessive levels of androgens circulating in female (a testosterone hormone increase), whose side effect includes thinning hair on scalp (androgenic alopecia).

Hyperandrogenism also appears to have a close link to increased DHT activities according to Naturepathic Doctor News & Review. As you all know, DHT (Dihydrotestosterone) is your enemy when it comes to hair loss.

dht inositol alopecia hair loss

DHT is a converted form of testosterone by 5-alpha-reductase enzyme. When DHT attaches itself to androgen receptors on hair follicles, it causes your follicles to become miniaturized.

As your hair is getting thinner due to this miniaturization, it will eventually lead to what you call the most common form of hair loss – androgenetic alopecia (thinning on the crown, sides and edges, diffused thinning, as well as receding hairlines are the symptoms of AGA).

In other words, hyperandrogenism can result in hair loss due to an abnormal increase of testosterone in your body and skin’s increased sensitivity to DHT.

What is PCOS?

PCOS (Polycystic ovary syndrome) is a hormonal imbalance issue that affects up to 10% of women. It is often caused by two reasons – Glucose (insulin resistance) and androgen metabolisms (androgen excess). If you have PCOS and are currently experiencing hair loss, it’s likely to be due to the latter – androgen metabolism with overproduction of androgens in your body.

So is there any natural treatment for high androgen levels? Read along.

Hyperandrogenism treatment? Studies show inositol is your answer

One of the natural ways to treat hyperandrogenism is myo-inositol according to a number of studies (examples here and here).

A study published in the European Journal of Endrocrinology shows that a group of women with PCOS who received 1200 mg of myo-inositol per day for 12 weeks showed great improvement in decreases in androgen excess as well as decreases in weight loss.

Success stories

PCOS related hair loss

We also came across this blog who had great success on stopping her thinning hair using inositol. She had PCOS and one of the symptoms she experienced was severe hair loss.

To sum up her story, her hair loss stopped when she was taking 1500 mg/day. She is also additional taking inositol and choline for PCOS. For people who are experiencing PCOS’ related hair loss, she recommends inositol powder – A lot cheaper than buying inositol capsules.

No PCOS related hair loss

We found another success story in a forum. She talks about her bald patches of hair loss growing back only in 1.5 month. She initially started taking inositol for OCD and noticed her hair was unexpectedly growing back. She says she took 2-4 grams per day to see the effect.

Choline and inositol for hair growth

Now we talked about inositol, let’s briefly review choline.

Choline is an essential water-soluble nutrient found in every cell of the body. The choline role in body includes the proper functioning of the liver and nervous system, brain development, and maintaining the integrity of cellular structures.

Another important role of choline is in neurotransmitter synthesis, which is related to maintaining proper cognitive brain functions such as memory and regulating motor control.

How much choline a day? When it comes to daily intake recommendation, it’s 425 mg/day for women and 550mg/day for men according to Oregon State University.

NOTE: The highest choline-rich food is an egg yolk, which provides 680 mg per 100 grams  according to a study.

Why take choline with inositol for hair growth?

Choline and inositol benefits: One of the main roles of inositol and choline is to keep the liver healthy by preventing the excessive accumulation of fats (or technical term – cholesterol and triglycerides).

With the help of inositol and choline, the liver can provide essential vitamins and minerals to every cell of your body including hair follicles. If the liver is not in good shape, your hair follicles don’t get proper nutrition, thus premature hair loss can occur.

Chlorine inositol dosage for stimulating hair growth: According to the book Smart Medicine for Healthier Living, Pratical A-Z Reference to Natural and Conventional Treatments for Adults, it suggests that high doses of inositol is helpful for stimulating hair regrowth and recommends people to take 200 milligrams 2 times a day.

If you are also planning to add choline, which the book agrees is a good compliment to inostiol, it recommends to take an equal amount to inositol… thus 200 mg of inositol and 200 mg of choline twice a day.

However, based on our research, we noticed that quite a number of people seem to take a higher dosage of choline and inositol supplements. For instance, popular choline/inositol supplements such as this have inositol 500 mg and choline 500 mg per serving. When you go through the reviews, you will see quite a number reporting great results in hair growth.
