A viewer named Venkatesh asked Dr. John Watts, a dermatologist, trichologist and hair transplant surgeon in Hyderabad who has performed over 2,000 hair transplant surgeries, whether stopping Minoxidil affects everyone who has used it, or only some patients.
How Minoxidil Works
This makes Minoxidil fundamentally different from a cure -- it manages the symptom of poor blood supply to hair follicles rather than addressing why the hair is thinning in the first place for most users.
Dr. Watts explains that Minoxidil works by increasing blood supply to the hair roots. Applied topically, it acts as a dilator, widening the diameter of the blood vessels that carry nutrition to the hair roots -- allowing more nutrients to reach them.
Why Stopping It Usually Reverses Progress
"Minoxidil provides temporary hair growth as it does not act against the cause of baldness i.e the DHT but only helps in supplying nutrition to the hair for growth. Hence, once you stop using it, the hair loss will continue as before and the achieved results would be lost again," Dr. Watts warns. This is different from Finasteride, which directly targets and blocks DHT, the underlying cause of baldness -- Minoxidil's role is purely to boost blood supply.
The One Exception
There is an exception, according to Dr. Watts: people whose hair loss is linked to nutritional deficiency rather than DHT. This includes conditions such as Telogen Effluvium, or hair loss triggered by crash diets, keto diets, water fasting, or intermittent fasting that cuts down essential nutrients. "If these people restart taking proper nutrition along with Minoxidil besides giving importance to a healthy lifestyle and diet, their hair growth will continue even if they stop Minoxidil at some point in time. This is because their hair loss is linked to nutritional deficiency only," he explains.

Frequently asked questions
Does hair loss come back after stopping Minoxidil?
Yes, for most users. Dr. Watts explains Minoxidil only boosts blood supply to the hair roots -- it doesn't block DHT, the actual cause of baldness -- so stopping it usually reverses the gains.
How is Minoxidil different from Finasteride?
Finasteride directly targets and blocks DHT, the hormone that causes baldness, while Minoxidil only increases nutrient supply to hair roots.
Is there any case where stopping Minoxidil doesn't cause hair loss to return?
Yes -- if hair loss was linked to nutritional deficiency (such as Telogen Effluvium or crash dieting), maintaining proper nutrition can sustain hair growth even after stopping Minoxidil.
