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.

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.
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.
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.

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.

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.
