Best Stem Cell Hair Growth Serums: Do They Really Work?

Act and Acre, Hairprint, and Vegamour offer stem cell hair growth serums to address thinning hair and hair loss. With its ability to provide deep hydration, stimulate hair growth, and target signs of premature aging follicles, we found that Act and Acre’s serum is the best option overall. Hairprint’s serum is the most affordable option and can improve the scalp microbiome, while Vegamour is ideal for improving hair density and thickness.

Stem cells can regenerate into other cells with specialized functions, making them a valuable tool in tissue regeneration. Stem cell culture preserves stem cells outside of their normal environment and may benefit hair growth by stimulating inactive or damaged hair follicles. Act and Acre, Hairprint, and Vegamour use plant stem cells from apple or curcumin (turmeric). Though plant stem cells are a relatively new ingredient and aren’t yet FDA-approved, they’re unlikely to cause side effects

Read on for our complete review of the best stem cell serums for hair growth, including a detailed overview of each brand. In addition, we spoke with Dr. Jonathan Rick, a board-certified dermatologist, so we could better understand the causes of hair thinning and hair loss.

Act and Acre vs. Hairprint

Act and Acre and Hairprint both utilize apple stem cells for hair growth. However, Act and Acre also provides deep scalp hydration and addresses signs of premature aging in hair follicles with bamboo, pea sprout, aloe vera, and hyaluronic acid. Hairprint, on the other hand, encourages a healthy scalp microbiome with radish root and coconut milk culture. Act and Acre is more expensive at $86 for a 2.2-ounce bottle, compared to $55 for a 1.7-ounce bottle of Hairprint’s serum.

Act and Acre vs. Vegamour

Act and Acre’s stem cell serum with Swiss apple stem cell extract supports hair follicle health and hydrates the scalp to promote hair growth. Vegamour, on the other hand, uses curcumin stem cell extract to help naturally block DHT, an androgen that contributes to hair loss. Act and Acre is not the more affordable option at $39 per ounce, compared to $64 for a one-ounce bottle of Vegamour.

Does Act and Acre Stem Cell Serum Work?

Act and Acre Stem Cell Serum uses the brand’s H2-Grow Complex™ to address hair loss, hair thinning, and scalp irritation. It includes:

• Swiss Apple Stem Cells (2%) Extract promotes hair follicle health. Apple extract has been found to increase hair length, weight, thickness, and density in animal studies. Further research is required to confirm these results in humans.
• Bamboo and Pea Sprout Blend promotes scalp elasticity and hydration, which may facilitate hair growth. Clinical research has found that topical pea sprout extract improves hair density.
• Aloe Vera soothes the scalp and supports scalp hydration. While the healing benefits of aloe vera are well-documented, there’s no research directly linking it to hair growth.
• Hyaluronic Acid deeply hydrates the scalp, reducing dryness and itchiness.

Act and Acre Reviews

In general, customers love that Act and Acre is a lightweight, fast-absorbing serum that improves scalp health and hair quality. However, some customers didn’t experience a noticeable improvement in hair regrowth after using the serum.

Hairprint Stem Cell Serum Pros & Cons

Does Hairprint Stem Cell Serum Work?

Hairprint Stem Cell Serum is formulated to slow hair follicle aging with stem cells from rare alpine apples and encourage a healthy scalp microbiome with plant-based cultures.

• Apple Fruit Cell Culture Extract increased hair length, weight, thickness, and density in animal studies. Further research is required to confirm these results in humans.
• Radish Root Culture (leuconostoc ferment) encourages a healthy scalp microbiome. Additionally, radish root contains significant amounts of sulfur, which promotes keratin production. Keratin is an essential protein for hair growth. Radish root extract has also been found to support hair growth and development in mice, though further research in humans is needed.
• Coconut Milk Culture contains lactobacillus and cocos nucifera ferment to nourish hair and balance the scalp microbiome.

The brand’s holistic approach to hair health is particularly helpful for individuals who want to address the key causes of hair loss without harsh, medicated ingredients.

Vegamour GRO Hair Serum Pros & Cons

Does Vegamour GRO Hair Serum Work?

Vegamour’s GRO Hair Serum helps thicken, strengthen, and volumize hair with:

• Curcumin Stem Cell Extract is thought to prevent hair loss by acting as a natural DHT inhibitor and supporting IGF-1 and BMP4 production. DHT is a hormone that can shrink hair follicles; IGF-1 is a hormone that promotes hair follicle growth; and BMP4 is a polypeptide that plays an important role in hair regeneration.
• Red Clover may provide natural DHT-inhibiting properties and has been found to boost scalp health in people in the postmenopausal stage of life.
• Mung Bean is rich in copper, a mineral that encourages hair health, and is thought to prevent premature shedding.

Vegamour Reviews

Generally, Vegamour’s customers are satisfied with the serum’s results for hair loss and hair density. Many customers also note that it hydrates and conditions their hair. However, a few customers noted that they had trouble with the bottle dropper design and that the product is expensive.

So far so good!☆☆☆☆☆Mickey Read More “I am suffering from thinning hair in the front, I believe due to age...60+.....heard good reviews...wanted to give this a try...I have been using it for 3 weeks now and do see less hair loss as well as the serum does help give the appearance of MORE body, almost like a mousse. It is a tad bit oily, but again..acts like a conditioning hair product. Using a full dropper a day, I have only used half the bottle, so it is cost effective and I will continue to use it. Hope to see some more emprovement by the 2nd or 3rd month.” It works, but you must use it daily and consistently. Not an overnight fix.☆☆☆☆☆ Read More “I have been using this for 6 months now and it continues to work. I'm also using the shampoo and conditioner. The first 4 months I used it twice a day (morning and evening). Once I had a good amount of regrowth, I started using it once a day, and I haven't noticed any loss so far. I will continue to use it once a day for maintenance and we'll see how it goes. My only criticism is the dropper bottle design. It is impossible to fill the dropper adequately and can be difficult to portion out how much product one should use. A redesign would be useful.” Previous Next

What Are The Side Effects Of Stem Cell Serums?

Stem cell therapy derived from animal or human sources can lead to side effects including infection and unwanted immune response. Topical plant stem cell serums pose a far lower risk of side effects, as they’re derived from natural sources. However, scalp irritation and changes in hair texture are possible.

Before trying a stem cell serum, it’s best to speak with your healthcare provider to ensure it is safe for you to do so. In some cases, there may be an underlying cause that will need to be addressed.

A Word From Our Expert

— Dr. Jonathan Rick

There are many types of hair loss, many of which require evaluation by an experienced physician to adequately diagnose. However, androgenic alopecia is very common and treatable. This type of hair loss is caused by the interaction of hormones on hair receptors. Some people have hair that is very sensitive to hormones and notice more hair loss than others their age.”

When to Seek Emergency Medical Care

Seek emergency medical care while using stem cell serums if you experience symptoms of a severe allergic reaction, including:

• Skin rash, hives, or severe itching
• Swelling of the lips, throat, or tongue
• Shortness of breath
• Difficulty breathing
• Dizziness
• Fainting
