Hair Growth Serum FAQ

What's so special about FullyVital hair growth serum?

Our Enhance hair growth serum addresses multiple reasons behind hair thinning such as hormonal imbalances, reduced circulation, stress on hair follicles, free radicals and inflammation on the scalp. This combinations helps you grow thicker, fuller hair quickly.

Hair Growth Serum Ingredients:

For example, FullyVital serum contains caffeine and copper tripeptides to balance hormones such as DHT. It contains melatonin that serves as an antioxidant to fight the free radicals that damage your scalp. Our Enhance hair serum contains methyl vanillate and ginseng to increase circulation to the scalp.

Lastly, most other serums on the market come in a very small size of 30ml or 1oz. FullyVital hair growth serum contains almost double that amount, or 50ml/1.7oz.

The combination of these ingredients help FullyVital hair growth serum ingredients really stand out.

Will your hair serum make my hair oily or greasy?

Enhance hair growth serum is light-weight and leaves no residue behind. This means that it dries off completely by the following morning. Apply the thick hair serum at night and leave-on overnight. Style your hair normally the next day without needing to wash your hair.

Is Enhance hair growth serum natural and drug-free?

Enhance hair serum is 100% natural, vegan and free of drugs, hormones and chemicals. It contains no benzoates, phthlates, parabens or any other harmful chemicals. It is also cruelty-free and has never been tested on animals.

What is FullyVital's return policy for the serum?

If you do not like our hair growth serum for any reason, you can send them back to us for a a full refund (minus shipping and handling). Just email us at to start your return.

What is the best serum for hair growth and thickness?

The best serum for hair growth and thickness is one that addresses multiple reasons behind hair thinning. A hair serum that helps balance hormones on the scalp, improves circulation and contributes to a healthy scalp environment can help grow thicker, fuller hair. Enhance thick hair serum is formulated to fight hair thinning by addressing the root causes behind hair loss.

Which serum is better than minoxidil?

While minoxidil is a FDA-approved treatment for hair loss with proven efficacy, some people might seek alternatives due to side effects or lack of desired results. Though it's hard to categorically state which serum is better than minoxidil, as effectiveness can vary based on individual response, there are options that have shown promise.

Redensyl and capixyl are two plant based actives with promising scientific data for hair growth. A recent published study compared redensyl + capixyl to a minoxidil 5% preparation. The research evaluation showed significantly better recovery in the group treated with Redensyl and capixyl than in the group that received minoxidil treatment.

Natural hair growth serums that contain ingredients such as caffeine and rosemary oil, among others, have also shown potential. For instance, a study published in 2017 indicated that caffeine was as effective as 5% minoxidil in promoting hair growth, but with fewer side effects.

Bottom line: which serum is better than minoxidil:

A serum which contains the above ingredients can theoretically perform better than minoxidil. FullyVital has the above ingredients and even more actives to fight hair thinning and regrow hair.

How long does it take for hair growth serum to work?

The time it takes for a hair growth serum to show visible results can vary widely based on the product's ingredients and the individual's unique hair growth cycle and response to treatment.
For instance, with minoxidil, one of the most well-studied and effective hair growth ingredients, studies show that significant results usually become noticeable after about four months of consistent use. However, peak hair regrowth may not be reached until approximately one year of ongoing treatment.

A natural hair growth serum or thick hair serum may also require several months of use before noticeable results are seen, though this can vary based on the specific product and person.

It's important to understand that hair growth is a slow process. Human hair naturally grows about half an inch per month, and that's under optimal conditions. So, patience is key when using any hair growth serum.

Is biotin hair serum good for hair growth?

Biotin hair serum

can support hair growth in people who experience hair thinning due to a biotin deficiency. The hair follicles and the skin on the scalp can both benefit from a biotin hair serum. However, it's important to note that there is little evidence of biotin supplements or serum helping individuals without a biotin deficiency.

What's the difference between hair growth oil and hair growth serum?

While both hair growth oils and serums aim to promote hair growth, the difference lies mainly in their composition, consistency, and method of application.

Hair growth oils are often composed of natural oils such as coconut, jojoba, argan, or castor oil, which are known for their hydrating and nourishing properties. These oils can also contain specific nutrients and vitamins like Vitamin E, which may help stimulate hair growth by enhancing blood circulation in the scalp. They're typically heavier in consistency and are often applied directly to the scalp and hair, left in for a period of time, and then washed out.

Hair growth serums, on the other hand, can be either water-based or oil-based and typically contain a higher concentration of active ingredients aimed at promoting hair growth, like minoxidil or natural DHT blockers. They're usually lighter in consistency and designed to be left in the hair without a rinse-off. The primary function of a thick hair serum is to penetrate deeper into the hair follicle to promote hair growth at the root.

Difference between hair oil and hair growth serum:

In conclusion, both serve a purpose and can be used together for a comprehensive approach to hair growth. The choice between an oil or a serum may depend on your hair type, personal preference, and specific hair needs.
FullyVital thick hair serum is lightweight and water based. Therefore, it can be left in overnight without needing to wash it out the following day.

How do I use FullyVital thick hair serum?

It is important for any serum to be applied to your scalp for many hours, otherwise the effects are not as pronounced.

Thick Hair Serum - How to use

The way to use FullyVital thick hair serum is to apply it every evening after brushing your hair. The serum is lightweight and will dry off by the morning, so you can style your hair as usual without needing to wash it off.

If you want even faster results, apply our thick hair serum to all thinning areas in the morning and in the evening. Our hair growth serum ingredients are top notch and can really help boost hair growth and thickness.

Do you make a separate hair growth serum for black women?

A serum specifically created for hair growth targets hair follicles at the root and improves the health of the scalp. This allows the scalp to grow healthy hair. While black women's hair has a unique texture and structure, the serum does not target the hair but the hair follicle cells. For this reason, the same serum growth serum works for black women.

What serum is FDA approved for hair growth?

Minoxidil, available over the counter and most commonly known by the brand name Rogaine, is FDA approved for hair growth. It's suitable for both men and women. It's applied topically and helps to stimulate hair follicles, though users report mixed results.

Can I see pictures of hair growth serum before and after?

Yes, we share our testimonial videos and pictures of hair growth serum before and after. You can find the testimonial videos on the results page, and you can find the hair growth serum before and after pics up above on this page.

Do hair growth serums actually work?

Hair growth serums can balance hormonal imbalances on the scalp, improve circulation and help create a healthy scalp environment for hair growth. A hair growth serum with science-backed ingredients can help you achieve thicker, fuller looking hair in 3-6 months.

What is the best hair product for fast hair growth?

The best hair products are typically formulated with science backed ingredients with multiple studies. In our experience, using multiple products at the same time improves hair health and density vs just one product at a time. For example, a supplement, serum, hair brush and roller combination works much better than a hair serum alone.

Which hair growth serum is the best?

The best hair growth serum contains science backed ingredients and addresses multiple reasons behind hair thinning. It contains nourishing ingredients like biotin, antioxidants to prevent free radical damage and circulation enhancers. Enhance hair growth serum contains all the above, plus it also contains dihydrotestosterone (DHT) blockers to fight against male or female pattern hair loss.

What is the history of hair growth serum for women?

Women have been on a quest for fuller, healthier, and longer hair for centuries. The concept of using potions or serums to enhance hair growth is not a recent invention, but rather a practice that has evolved significantly over time.

Historically, ancient Egyptians were known for their attention to beauty and hair care. As early as 1550 BC, Egyptian women were using concoctions of animal fats and other natural ingredients as a means to enhance hair growth and maintain hair health. Similarly, in ancient Rome, noblewomen used mixtures of olive oil, botanicals, and spices to stimulate hair growth and maintain their locks.

Meanwhile, in traditional Ayurvedic medicine in India, potent herbs like bhringraj, amla, and fenugreek have been used for millennia to promote hair growth and reduce hair loss.

In more recent history, the 19th and early 20th centuries saw an increased interest in hair care, but many potions and tonics advertised as hair growth miracles often contained harmful ingredients and made unfounded claims. It wasn't until later in the 20th century that scientific understanding of hair growth and loss began to significantly develop, leading to the creation of more effective and safer products.

The first FDA-approved hair growth treatment, minoxidil, initially a blood pressure medication noted for its side effect of hair growth, was developed in the 1980s.

Hair growth serum for women:

This marked a significant milestone in the evolution of hair growth serums for women, shifting the approach from generally natural or pseudoscientific remedies to evidence-based treatments.

Today, hair growth serums for women are a blend of these traditions and modern scientific advancements. These serums often contain a mix of natural ingredients, like essential oils and botanical extracts, and scientifically-proven ingredients, like minoxidil or natural DHT blockers. As our understanding of hair growth continues to advance, we can anticipate the continual evolution of these products, always aiming for safer and more effective solutions for hair growth.

How often should I use a hair growth serum?

The frequency of using a hair growth serum largely depends on the specific product and its instructions. Generally, many serums recommend daily use for optimal results. For instance, minoxidil, an FDA-approved hair growth treatment, typically suggests application once or twice daily. Natural or botanical-based serums may also recommend daily use, but the frequency could differ based on the product's formulation. It's essential to follow the usage instructions provided by the manufacturer to ensure safety and effectiveness. FullyVital hair serum is recommended to be used 1-2 times per day. Our hair growth serum ingredients are top notch and can drive fantastic results.
