Hair loss is common, and for many men it becomes noticeable long before they expect it. Understanding why it happens makes it easier to recognise when something is normal — and when treatment may help.
This guide explains how hair grows, why hereditary hair loss occurs, and how Regaine can support regrowth.
How Hair Grows
Every strand of hair follows a natural growth cycle with three phases:
-
Growth phase (anagen)
-
Transitional phase (catagen)
-
Resting and shedding phase (telogen)
At any time, most of your hair is in the growth phase. In hereditary hair loss, this cycle changes. The follicle becomes smaller, the growth phase shortens, and each new hair becomes thinner and shorter than the one before.
Why Hair Loss Happens
1. Natural, everyday shedding
The average adult has around 100,000 hairs, and it’s normal to shed 40–120 hairs per day. This is part of a healthy renewal process.
2. When shedding becomes noticeable
If you see more hair than usual in your brush, shower, or on your pillow — and especially if you notice thinning on top or a receding hairline — you may be experiencing more than routine shedding.
A few possible causes include:
-
Medical conditions
-
Medications
-
Poor nutrition
-
Harsh styling or hair care
-
Severe or prolonged stress
But the most common cause, by far, is hereditary hair loss.
Hereditary Hair Loss (Androgenetic Alopecia)
Hereditary hair loss, also called male pattern baldness, is responsible for the majority of hair loss in men.
In this type of hair loss:
-
Genetics, hormones, and age shrink the hair follicles.
-
Each growth cycle produces finer, shorter, less visible hair.
-
Eventually, some follicles stop producing hair altogether.
This process is gradual but progressive, and without treatment, it typically continues over time.
Can You Treat Hereditary Hair Loss?
Yes. While you can’t change your genetics, you can take steps to slow the process and support regrowth.
Regaine® Extra Strength Foam or Solution is clinically proven to treat hereditary hair loss in men. The active ingredient, minoxidil, works by:
-
Increasing blood flow around the follicles
-
Helping reverse follicle shrinkage
-
Encouraging follicles back into the active growth phase
-
Supporting thicker, stronger regrowth
Many men notice visible results within a few months of consistent use.
When to Consider Treatment
You may benefit from Regaine if you’re noticing:
-
Thinning on the crown
-
A more pronounced hairline
-
More shedding than usual
-
Hair that looks finer or weaker
Regaine works best when used early, before follicles have stopped producing hair entirely.
Regrowth varies. The product will not work for all users. Always read the label and patient information leaflet before use.
