Stimulate Your Scalp.. Accelerate Your Hair Growth

The STIMULATE Hair Growth Serum not only stimulates hair follicles for rapid hair growth, but also produces increased blood flow in the scalp, strengthens hair to prevent further breakage, and balances oil production. It does it all! 

STIMULATE is a daily-use hair growth serum designed to increase hair growth that enhances hair density, strength, and durability while treating your scalp.

Formulated with key ingredients like Biotin, Pea Sprout Extract, Castor Oil, Soy Protein, Pea Protein, Peppermint Oil, Vitamin E, and Coconut Oil this serum gets to work by stimulating follicles to promote hair growth for people who are experiencing any of the common hair loss issues such as: Male Pattern Hair Loss, Female Pattern Hair Loss, Androgenetic Alopecia, Hashimoto’s Disease, and more.

STIMULATE is free from sulfate, parabens, phthalates, and synthetic dyes. We pride ourselves on using natural ingredients, which ensures this is gentle enough for daily use. We do, however, use a slight fragrance (Peppermint Oil). 

STIMULATE Hair Growth With These Key Ingredients

1. Biotin

Known as vitamin B7, is a widely known ingredient for natural hair growth. It stimulates keratin production in hair and can increase the rate of follicle growth. When added to a shampoo or conditioner, with regular use, it can help stimulate the scalp, while adding the right nutrients to provide strength and fullness. [1]

2. Peppermint Oil

Helps increase blood circulation in the scalp. Its main ingredient, Menthol, seems to be capable of increasing the number and depth of hair follicles. A study suggests that it even performs better than minoxidil at even concentration. [2]

3. Vitamin E (Tocopherol)

Research has also shown that Vitamin E oil can improve dry hair and/or dry scalp, infusing both with moisture and also locking it in, so that the softness and hydration are long-lasting. Some studies also show that Vitamin E oil may increase circulation to the scalp. This temporarily increases blood flow to the area helps to enhance the health and strength of the hair follicles. [3]

4. Arginine (from Pea Protein)

The amino acid L-arginine supports protein synthesis through the transport of nitrogen. It improves blood flow in the scalp, increases fiber strength, reduces hair loss, and stimulates hair growth. [4]

5. Pea Sprout Extract

Pea Sprouts are very beneficial for hair growth, feeding both the scalp and hair with essential nutrients and antioxidants to refresh and revitalize hair from the root. Studies have shown that Pea Sprout Extract can help shorten the Telogen phase of the hair growth cycle helping to strengthen hair follicle stem cells. [5]

Protect & Strengthens Hair With These Key Ingredients

1. Glycerin

Glycerin's ability to attract and maintain moisture makes it extremely beneficial to the scalp's overall health. Adequate hydration of the scalp's skin can prevent a host of issues, including dandruff and oil overproduction. Healthy hair starts at the scalp, making scalp health paramount in treating hair concerns. [6]

Other benefits include:

- Regulates Sebum Production

- Antimicrobial Properties

- Moisturizer For Dry Hair

- Improves Overall Scalp Health

- Strengthens Hair

- Targets Frizz

- Can Aid in Hair Growth

2. Coconut Oil

Coconut Oil possesses medium-chain fatty acid elements including lauric acid, capric acid and others that disrupt fungal, viral and bacterial cell membranes, leading to cell death. These antifungal and antimicrobial properties are what set it apart from other oils. Coconut Oil moisturizes and nourishes the scalp, alleviating the dryness that causes flaking. [7]

3. Hydrolyzed Soy Protein

Enhances hair manageability, improves the body and texture of hair, improves feel and dry comb properties, contains cystine for hair strengthening and nourishment. [8]

4. Castor Oil

Castor Oil has natural antibacterial and antifungal properties and is high in Vitamin E, minerals, proteins, and omega -6 and -9 beneficial fatty acids. [9]

But the most important and beneficial acid it contains is ricinoleic acid (which is 90% of its nutritional content). This acid helps increase circulation to the scalp and improves hair growth. It nourishes the hair roots so that hair grows stronger, and balances scalp pH, which keeps the scalp functioning at its ideal oil levels.

It also prevents infections such as folliculitis, a condition that causes inflammation of the hair follicles (and ultimately hair fallout).

5. Hydrolyzed Pea Protein

Rich in essential amino acids, hydrolyzed pea protein allows for tinier particles of proteins to bond to the hair, linking together to form a protective structure that prevents cuticle cracking and damage and boosts the hydration and moisture retention in each strand. Its protective nature also shields locks from heat damage from dryers and irons. [10]

6. Vitamin E 

Research has also shown that Vitamin E oil can improve dry hair and/or dry scalp, infusing both with moisture and also locking it in, so that the softness and hydration are long-lasting. Some studies also show that Vitamin E oil may increase circulation to the scalp. This temporarily increases blood flow to the area helps to enhance the health and strength of the hair follicles.

  • FAQ

Application of the STIMULATE hair growth serum is simple! Just follow the steps below:

1) Using one full dropper, touch the dropper directly to your scalp and release a small amount of serum

2) Move to another spot on your scalp and release a small amount of serum

3) Continue this process until you have used the entire dropper of serum (apply the serum to all areas of your scalp, even if your hair thinning or hair loss is isolated to one area. This will help with scalp wellness and with the prevention of future hair thinning or hair loss.)

4) Take 30 to 60 seconds and massage the serum into your scalp using your fingertips ensuring an even spread (if a warming sensation is felt, that's completely normal as the serum is stimulating the blood flow. If you don’t feel any warming, that’s ok too! Everyone reacts differently - but the serum is still working.)

5) Allow to settle for at least 6 hours before rinsing or a showering

6) Wash hands after use

Key Essential Ingredients


Biotin is a B vitamin that helps the body convert nutrients into energy. It’s involved in the synthesis of fatty acids and glucose and is one of the building blocks of thick, healthy hair.

Peppermint Oil

Peppermint essential oil is a vasodilator, which means it can increase blood to the hair follicles, keeping the hair itself as strong as possible and much less likely to fall out.

Coconut Oil

Coconut oil has been proven to reduce protein loss from the hair, so your hair stays thicker and stronger. This is especially important in areas of hard water. Helps protect and soothe the scalp without being greasy or messy.

Hydrolyzed soy protein

Hydrolyzed Soy Protein is a water-soluble protein derived from soy that will strengthen and mend hair fibers. It increases hair's ability to hold moisture while adding shine and smoothness.

Hydrolyzed pea Protein

Rich in essential amino acids, hydrolyzed pea protein allows for tinier particles of proteins to bond to the hair, linking together to form a protective structure that prevents cuticle cracking and damage and boosts the hydration and moisture retention in each strand. Its protective nature also shields locks from heat damage from dryers and irons.

Castor Oil

The oil’s ricinoleic acid increases scalp blood flow, which can promote healthier hair and growth while also cutting down on inflammation.

Pea Sprout Extract

In addition to its anti-inflammatory and anti-oxidant properties, pea sprout extract has been shown to have direct effects on hair growth by stimulating the expression of genes FGF7 and noggin, two well-known signaling compounds important for the induction of new hair growth.

Vitamin E

Vitamin E helps regulate the production of oils in the scalp. So if your scalp gets oily (greasy hair) or dry easily then the addition of Vitamin E to your diet could help normalize this.

Polyquarternium 10

They create a film over the damaged parts of hair fibers to protect against external aggressors, and to improve the quality of the hair surface. Polyquaternium-10 is a high-performing multitasker used to fight frizz, improve hair manageability, and provide defined and bouncy curls.

Stronger hair

I have thin blonde hair and have tried finding a product that will help my hair be less brittle after styling daily. After using this for a few weeks I have noticed how soft and stronger my hair is at the ends. Am excited to keep seeing results!

Will be buying this again!

First off let me say that I bought this for my boyfriend and I to use for thinning hair and to increase hair growth. I cannot say that I have noticed a difference in these areas, but I have only used half a bottle so far. HOWEVER, I absolutely love this stuff and will continue to buy it because It makes my hair feel so soft. My hair feels softer and more healthy feeling after using this stuff than any expensive hair product I have ever used from Sephora/Ulta.

It's my new FAVORITE

After the first try I am in love with this stuff. My hair feels silky and strong. I’m very impressed, I wasn’t expecting such awesome results. As for thickness, it feels better but time will tell how good it can get.

Softer and Thicker Hair

This conditioner smells great. I just started using it a few days ago and already my hair feels full and soft and thicker.. I can’t wait to see what this wonderful product will do in a month to my hair.

Making a BIG difference for me.

I am on my second bottle of this serum and have found it to make a huge difference in the overall health of my hair. My natural hair is fine and brittle. After having used this product for a while, I am finding my hair stronger, healthier and thicker with increasing hair growth all the time. The product is easy to apply. Highly recommend to all who are struggling with hair loss and/or fine hair!
