Effective Natural Hair Growth Stimulating Ingredients

Formulated with the goal to maximize scalp blood circulation, Scalpezol conditioner contains these botanicals:


Capsaicin is an active component of chili peppers. Topical application to skin have shown to increase blood flow significantly. A scientific study from 2007 suggests that capsaicin may stimulate the production of insulin-like growth factor (IGF-1). Higher levels of IGF-1 may stimulate hair growth [1]. Animal studies, such as the one conducted by Lee and Ahn, have indicated that when capsaicin is applied, hair growth may quickly start [2] and may continue for an extended period of time.


Rosemary is an herb from the mint family. It helps promote blood circulation and reduce inflammation. Rosemary is used to reduce hair loss and promote the growth of new hair. A comparative study revealed that rosemary promotes hair growth as good as Rogaine [3]. Another study suggests that when rosemary is added to shampoo, it inhibits yeast growth and reduces Pityrosporum, which promotes good antidandruff activity [13].

Red clover

Red clover is a plant from the bean family that is found across Europe and Asia. A clinical study published in Obstetrics and Gynecology International found that red clover extract may increase hair growth for those experiencing hair loss due to alopecia [4]. Because red clover is high in isoflavones, it may be beneficial in promoting blood flow to the scalp and in growing stronger and healthier hair [4].

Grapeseed Oil

Grapeseed oil is extracted from the seeds of grapes. It contains linoleic acid, which is one of the most effective fatty acids at preventing the body from forming the hormone, DHT. DHT has been linked to male pattern baldness. A Japenese study discovered that proanthocyanidins, the main compound found in grapeseed oil, is what stimulated hair growth 230% more than the control group [12].

Scalpezol dietary supplement contains powerful DHT blockers and blood flow boosting herbs:

stinging nettle

Stinging Nettle Extract

Stinging nettle extract comes from the root of the stinging nettle a plant found in Europe and Asia. It helps treat hair loss, promote hair regrowth, and cure dandruff. A 2005 study completed by the Journal of Herbal Pharmacotherapy demonstrated that stinging nettle can inhibit DHT production [14]. Another study published in Andrologia [5] also suggests that stinging nettle can minimize the risk of DHT hormone-related hair loss.

pumpkin seeds

Pumpkin Seed Extract

Pumpkin seed extract comes from the seeds of pumpkins. It blocks the action of 5-alpha reductase and has antiandrogenic capabilities. A 2014 randomized, double-blind, placebo-controlled trial revealed that men who took pumpskin seed extract had 40% more hair growth than those in the placebo group [15]. Another study showed that pumpkin seed extract stimulates hair growth at an order of magnitude greater than what is seen with traditional hair loss medication [6].



Hibiscus are flowering plants found in tropical regions of the world. A study published in the Journal of Ethnopharmacology shows that hibiscus supplements help build stronger and healthier hair [7] due to their amino acids. They also reduce scalp irritation by promoting healthy blood flow to the scalp.

apple peel

Apple Peel Extract

Apple peel extract are nutrients found in the peels of apples. These peels have high antioxidant properties that may make them powerful tools in promoting good scalp health. The British Journal of Dermatology demonstrated that apple peel extract is particularly effective in combating hair loss. Apples are high in the chemical procyanidin B-2. Low levels of this chemical have been linked with male pattern baldness [8].



Nattokinase is an extract that is taken from natto. Natto are fermented soybeans, which are a popular food in Japan. Nattokinase has a beneficial impact on blood flow throughout the body, as well as the scalp. In an article published in Acta Haemotology, researchers found that nattokinase can also help address hair loss by stimulating healthy blood flow to the scalp via its high fibrinolytic activity [9]. A healthy amount of blood flow may promote hair growth, providing the hair follicles with necessary nutrients for growth.



Apigenin is a naturally occurring compound found in many fruits and vegetables. Apigenin has anti-oxidant properties that may be an effective intervention for issues including hair loss [10]. Through a multi-stage mechanism, primarily based on stimulating the growth of dermal hair cells, apigenin may stimulate effective hair growth. According to a study that was published in 2009 on apigenin and hair loss, this substance helps prevent the body from forming TGF-B1. This substance can inhibit the growth cycle for human hair [11].



Pycnogenol is an extract that comes from pine tree bark. It is one of the purest and most potent natural antioxidants and anti-coagulants. Scientists from Switzerland reported in European Heart Journal that the pycnogenol reduces oxidative stress and increases blood vessels’ ability to relax by 32% [16]. Increase in circulation provides nutrients and antioxidants to hair follicles. Ensuring proper blood flow to the scalp is of the most importance in regenerating hair follicles and rejuvenating aged hair follicles.

Unlike conventional hair growth pills, Scalpezol do not contain stimulants and harsh chemicals and is gentle on your stomach. It is a healthy supplement choice and its ingredients have many additional health benefits, such as: support for strong hair and nails, glowing skin, hormone balancing, anti-inflamatory and anti-aging properties.
