Blockers and inhibitors of dihydrotestosterone (DHT) are among the most potent agents for promoting new hair growth. The substance that is responsible for hair loss is called DHT, and it is derived from testosterone.

It is believed that minoxidil works by partially expanding hair follicles and prolonging the growth phase of hair. This is how it works. Finasteride reduces the quantity of the hormone dihydrotestosterone (DHT) that is produced in your body, which is how it works.

  8. Saw palmetto. Saw palmetto extract has the potential to inhibit the enzyme known as 5 alpha-reductase (5AR), which is responsible for the conversion of testosterone to DHT.
  9. Ginseng. Ginseng includes saponins and gintonin, both of which have the potential to treat alopecia in people. Saponins have been found to stimulate hair growth in mice by blocking 5AR, while gintonin has the potential to treat alopecia in humans.
  10. MSM. MSM stands for methylsulfonylmethane, which is a chemical substance containing sulphur that is generated from plants. It has been discovered that supplementation with MSM leads to considerable improvements in the appearance and condition of hair and nails, as determined by expert grading and participant self-assessment.

Best for men


Hims provides a number of subscription products for the treatment of male hair loss. These products contain either minoxidil, finasteride, or both of these ingredients together. The company also sells a range of vitamins, including biotin gummies, amongst other options.

84.4 per cent of participants with androgenetic alopecia maintained good hair density following initial therapy when using a topical minoxidil-finasteride combination, according to a study that was conducted in 2015 utilising 45 male volunteers who were trusted as sources of information.

Participants in the study were able to keep their hair in better condition by combining the two components in their routines.

Customers who have already created an account with HIMS have the ability to schedule an online consultation with a qualified medical professional in order to receive recommendations regarding the items that are most suitable for their needs.

However, while having an A+ rating with the Better Business Bureau, Hims, Inc. has received some evaluations from customers that are less than fantastic. The overall 1.33 average rating out of 5 stars that the company has received is due to sexual dysfunction items as well as complaints about being charged for products after informing the company of the wish to cancel the subscription to such products.

When it comes to hair products, in particular, consumers have remarked on the efficacy of the combination of minoxidil and finasteride in particular.

Hims also provides customers with a full money-back guarantee for the first ninety days after purchase. It may take up to 48 hours to cancel a subscription, and you have to do so at least two days before the charge for the next month or you will be charged for an additional month’s worth of service.

Shea butter is included in the shampoo to moisturise the hair, make it more manageable, and shield it from breaking and damage.

Frequently asked questions

When will I get results from using products that promote hair growth?

The effects of hair growth products do not appear immediately. The majority of products will begin to show some kind of effectiveness within a few months.

It will take your product several weeks to begin stimulating hair follicles, and even after that, it will be at least a couple of months before you start to see new hair growth.

Although actual hair growth can take several months, the majority of hair products can boost the look of your hair’s thickness in just a few weeks.

When it comes to hair growth, which is more effective: serums or supplements?

Supplements, on the other hand, work from the inside out, in contrast to serums, which work from the outside in. If you want the best possible outcomes, it’s best if you can use both kinds of products at the same time.

As opposed to supplements, there are no studies that have been conducted that demonstrate the benefits of serums. On the other hand, in most cases, therapies that are applied topically work more quickly than those that are taken orally.
