capsaicin cayenne pepper soy isoflavone hair growth stimulating recipe formula
BENEFITS
  • Reverse hair loss
  • Stimulate new hair growth

You’ve probably heard about using cayenne pepper for stimulating hair growth.

But, is there any scientific evidence behind this folk hair loss remedy?

A 2007 study by a team of Japanese researchers says yes. In fact, they went even further.

The study shows that when you take capsaicin (a main component of various peppers including cayenne pepper) and isoflavone (an organic compound from soy) together, significant hair growth was observed in both mice and human participants.

There’s more: This combo worked so well for inducing hair regrowth in androgenetic alopecia (thinning hair) and alopecia areata (patchy hair loss) to a certain extent.

So what’s so special about these two ingredients – capsaicin and isoflavone?

The researchers found that both capsaicin and isoflavone have something in common: they increase a hormone called IGF-1 (Read more about IGF-1 and hair growth).

To be specific, both ingredients stimulate sensory neurons in the body, which then increase the production of CGRP (calcitonin gene-related peptide). The increased CGRP in turn signals IGF-1 to go up and stimulate hair matrix cells.

Here are before and after photos of the alopecia participants in the study:

As you can see, the participants show visually significant improvements with new hairs filled into the thinning / bald spots.

Ingredients

The participants were instructed to take 6 mg of capsaicin and 75 mg of isoflavone per day internally for 5 months.

So to follow the study, you can use either of these options:

  • Option 1: Natural foods (The most optimal way)
  • Option 2: Supplements (Quick and convenient)

Option 1: Natural foods

For isoflavones:
  • Miso: 1/2 cup contains 57 mg of isoflavones
  • Soybeans: 1/2 cup contains 56 mg of isoflavones (boiled version)
  • Soybeans: 1 ounce contains 42 mg of  isoflavones (dry roasted)
  • Tofu: 3 ounces of tofu contains 19 mg of isoflavones

The amount of isoflavone content varies depending on which data you are looking at. The above data is from USDA Food Composition Database and Oregan State University.

For capsaicin:
  • Cayenne pepper: 4.5 tsp contains 8 mg of capsaicin

According to an article from Department of Chemistry at King Saud University, cayenne pepper contains 1.32 mg of capsaicin per g (dry weight).

So, you will need take about 8 mg (7.92 mg to be exact) of dried cayenne pepper in order to get 6 mg of capsaicin content per day.

In general, capsicum fruit (aka various types of peppers – such as cayenne and chili peppers) contains from 2.19 to 19.73 mg/g of capsaicin (dry weight).

Option 2: Supplements

If you are looking for a more direct and convenient version, consider supplements that contain isoflavone and capsaicin.

Here are our recommendations:

How long?

Take consistently for 5 months to see results (just like the Japenese research).
