What You'll Learn
Topical minoxidil increases nail growth rate
Topical minoxidil has been shown to increase nail growth rate. In a 2021 study, researchers evaluated the efficacy of 5% topical minoxidil and 2.5 mg oral biotin in increasing nail growth rate over 28 days. The results showed that the minoxidil group presented a 19% increase in nail growth rate compared to a 13% increase in the biotin group.
Another study, published in the Journal of Cosmetic Dermatology in 2024, investigated the effect of topical 5% minoxidil spray applied twice daily, 2.5 mg biotin capsules, or a combination of both on 38 healthy volunteers. The results showed a positive effect of topical minoxidil on nail growth rate, with the group using only topical minoxidil showing greater longitudinal nail growth compared to the group using the combination of minoxidil and biotin.
The mechanism behind minoxidil's effect on nail growth rate is believed to be related to its ability to increase blood flow and supply to the nail. Minoxidil has been shown to upregulate the expression of vascular endothelial growth factor, which can increase blood flow and improve the oxygen supply to the nail, promoting faster nail growth.
Additionally, a survey of 74 patients using oral minoxidil found that 53% reported their nails grew more quickly, 37.9% reported stronger nails, and 36.4% noticed an improved appearance of their nails. These findings suggest that both topical and oral minoxidil may have a positive impact on nail growth and strength.
While the studies show promising results, it is important to note that further research is needed to fully understand the mechanism behind minoxidil's effect on nail growth and to determine the optimal protocol for usage in healthy and diseased nails.

Oral minoxidil may also help
The mechanism by which oral minoxidil increases nail growth rate is not yet fully understood. One theory suggests that minoxidil upregulates the expression of vascular endothelial growth factor in hair follicle dermal papillae, which may also occur in the nail apparatus, leading to increased blood flow and supply. Another theory proposes that the effect of minoxidil on nail growth may be due to mitotic stimuli directly on the nail matrix cells by over-regulation of the CYR61 and DUSP1 genes, rather than vasodilation.
While the exact mechanism requires further research, the available studies indicate that oral minoxidil may be a viable option for individuals seeking to enhance their nail growth and improve the overall appearance and strength of their nails.

Minoxidil's vasodilatory properties
Minoxidil is a potent direct-acting peripheral vasodilator, which was introduced in the early 1970s for the treatment of hypertension. It is capable of reducing blood pressure in most persons with resistant hypertension where therapy has failed with multidrug regimens.
The antihypertensive activity of minoxidil is due to its sulphate metabolite, minoxidil sulphate. It acts by opening adenosine triphosphate-sensitive potassium channels in vascular smooth muscle cells, causing vasodilation. Venodilation does not occur with minoxidil; thus, postural hypotension is unusual with its administration.
A recent study found that a 5% concentration of topical minoxidil applied twice daily can stimulate nail growth, with an average growth of 4.27 mm/month compared to 3.91 mm/month in untreated nails. The exact mechanism of minoxidil's effect on nail growth has yet to be determined, but its vasodilatory properties are believed to play a crucial role.
In conclusion, minoxidil's vasodilatory properties, which increase blood flow and supply, are likely responsible for its positive impact on nail growth.

Minoxidil's impact on nail disorders
Minoxidil is a conventional medication with a novel indication that has shown positive effects on nail growth rate. The drug is widely used for stimulating hair growth, and its effectiveness is linked to its vasodilatory property. As hair and nail structures are similar, and periungail blood flow is a factor in nail growth, it is assumed that minoxidil can also help nails grow faster.
A recent study showed that a 5% concentration of topical minoxidil can stimulate nail growth, with increased growth beginning in the first week of application. The mean growth of treated nails was 4.27 mm/month compared to 3.91 mm/month in untreated nails. Another study found that 53% of surveyed users reported that oral minoxidil helped their nail growth, with 37.9% reporting stronger nails and 36.4% reporting improved nail appearance.
The exact mechanism of minoxidil's action on nail growth is not yet fully understood. One theory suggests that it may increase blood flow to the nail by upregulating the expression of vascular endothelial growth factor, leading to increased oxygen supply and promoting nail growth. Another theory proposes that minoxidil may act directly on the nail matrix cells by over-regulating the CYR61 and DUSP1 genes, rather than through vasodilation.
While the results suggest that minoxidil can stimulate nail growth, further studies are needed to confirm its efficacy and safety in treating nail disorders. The protocol for using minoxidil in healthy versus diseased nails may differ, and on-and-off treatment periods may be considered to manage the autoregulation of nail blood flow, which can reduce the drug's effectiveness over time.
In conclusion, minoxidil shows promising results as a potential treatment for nail disorders characterised by slow nail growth. Its ability to increase nail growth rate and improve nail strength and appearance makes it a candidate worth considering for further investigation in this context.

Minoxidil and biotin together
Minoxidil is a potent vasodilator that has been used to treat hair loss and male pattern baldness. It works by increasing blood flow to hair follicles, stimulating hair growth, and prolonging the growth phase of existing hair strands. Oral minoxidil has been noted to result in patient satisfaction regarding nail strength, faster growth, and nicer appearance. A 5% topical minoxidil solution has been shown to increase nail growth rate, with the mean growth of treated nails being significantly higher than untreated nails.
Biotin, also known as vitamin B7, supports healthy hair and nails. It stimulates epidermal cell differentiation and aids in maintaining epidermal cell growth, which may help improve nail growth rate. Oral biotin has been reported to be successful in treating brittle nails and increasing nail thickness.
A recent study investigated the effect of topical 5% minoxidil spray, 2.5 mg biotin capsules, or a combination of both on nail growth rate. The results showed a positive effect of topical minoxidil on nail growth, with the group treated with the combination of minoxidil and biotin exhibiting lesser longitudinal nail growth but increased thickness. This may be due to the limited capacity of the nail matrix in producing material, resulting in shorter but thicker nails.
Another study evaluated the efficacy of 5% topical minoxidil and 2.5 mg oral biotin in increasing nail growth rate in healthy adults for 28 days. The results showed that the minoxidil group presented a higher nail growth rate than the biotin group, with no significant difference between the minoxidil and the minoxidil-biotin combination group.
While minoxidil and biotin have shown positive effects on nail growth, it is important to consult a healthcare professional before starting any new treatment or supplement regimen.
