Summary
Male pattern baldness, also known as male pattern thinning or androgenetic alopecia, is a hereditary condition that causes gradual thinning, usually around the temples, frontal hairline and top of the scalp.
It can begin from puberty onwards, including during the late teens and early twenties. At my Shuna Hammocks Trichology clinic, I look closely at the pattern of thinning, your family and medical history, scalp health and any other changes that may be contributing to your concerns.
Noticing changes in your hairline or seeing more scalp through the crown, for example, can be worrying, particularly if you are young or have always had thick hair.
Some men come to see me already convinced they have male pattern baldness. Others have been told their hair loss is due to stress, diet or ageing and simply want a clearer explanation.
I have worked with hair and scalp conditions for more than 27 years. My approach is to look at the whole picture (holistically) rather than make assumptions based on a single photograph, a single area of thinning, or your age alone.
What Is Male Pattern Baldness?
Male pattern baldness is the most common form of hair loss in men. It is also called androgenetic alopecia.
The condition develops when genetically susceptible hair follicles respond to normal levels of circulating androgens, particularly dihydrotestosterone, or DHT. Over time, affected follicles gradually produce finer, shorter and lighter hairs. This process is known as miniaturisation.
The change affects the front and upper areas of the scalp, while hair around the sides and back tends to remain stronger and unchanged.
Male pattern hair loss is gradual rather than patchy. A sudden bald patch, significant scalp inflammation or unusual breakage may suggest another hair or scalp condition and should be assessed separately.
Early Signs to Watch For
The initial changes can be subtle and often include:
- A gradually receding frontal hairline or deepening temple recession
- Increased scalp visibility through the crown or top of the head
- Hairs in affected areas becoming finer, lighter, or harder to style
- A noticeable reduction in overall hair volume or overall thickness
- A progressive shift over months or years rather than a sudden change.
The progression varies between individuals. Some men experience frontal recession first, while others notice diffuse thinning across the crown.
Why Does Male Pattern Baldness Happen?
It is sometimes assumed that men with pattern hair loss simply have too much testosterone. That is an oversimplification and most often incorrect; there are peer-reviewed studies proving this is not, in fact, true.
Male pattern baldness involves both genetic and hormonal factors. The important issue is how susceptible follicles respond to normal androgen activity rather than testosterone levels alone.
This is why two men of a similar age can have very different amounts of hair despite otherwise being healthy.
Diet, shampoo or scalp circulation do not cause androgenetic alopecia. Good nutrition and appropriate hair care still matter for general hair and scalp health, but they cannot change the genetic susceptibility of the follicles.
Can Male Pattern Hair Loss Start in Your 20s?
Yes. One of the concerns I hear regularly is: “I am only 21, 22 or 23. Am I too young for this?”
Male pattern hair loss can become noticeable at any time after puberty. An earlier onset does not mean that somebody will lose all of their hair quickly, but it is worth understanding the pattern rather than waiting and worrying about every change.
One young man contacted me because his hair was thinning around the crown and his hairline was receding more on one side. Other people had not yet noticed, but he could see a clear difference because his hair had previously been very thick and coarse.
This is quite common. You know your own hair better than anybody, so early changes can be noticeable to you long before somebody else sees them.
Does Family History Matter?
Androgenetic alopecia can be inherited from either or both sides of the family. Relatives can also experience varying degrees of thinning at completely different ages.
I frequently consult young men who feel confused because their father or grandfathers have full heads of hair. This does not rule out pattern hair loss, as genetic traits can skip generations or originate from maternal lines also.
During your consultation, we review your wider family history alongside the physical pattern on your scalp.
Stress or Male Pattern Baldness?
A period of physical or emotional stress can be associated with increased shedding, and changes in sleep, diet, illness or general health may also affect the hair cycle. That does not necessarily mean stress is responsible for recession around the temples or gradual crown thinning.
A 23-year-old man once contacted me because he had been told his hair loss was stress-related. The shedding continued after the stressful period had passed, leaving him unsure whether male pattern baldness was involved.
My response was that several things needed to be considered rather than assuming one explanation. His health, family history, lifestyle, pattern of loss and the hair itself all formed part of that assessment.
Sometimes more than one form of hair loss can be happening at the same time, which is another reason an individual examination can be useful.
How Shuna Hammocks (MIT, MRSM) Diagnoses Male Hair Loss
Your consultation at my Forest Row clinic is thorough and transparent.
- Detailed History Review: We discuss when you first noticed changes, progression, family history, health background, medication, diet, and lifestyle factors.
- Trichoscopy & Dermoscopy: I examine the hair and scalp under high magnification to analyse hair calibre, follicle density, and degree of miniaturisation.
- Differential Diagnosis: I evaluate whether secondary factors, such as scalp inflammation or temporary shedding, are compounding the issue.
- Medical Collaboration: If systemic checks or blood tests are indicated, I provide clear recommendations and can include your specialists into the diagnosis.
A Patient’s Experience
John from Haywards Heath originally sought advice for a persistent scalp condition. Like many men, he had assumed there was little point discussing his pattern thinning.
After addressing his scalp health and discussing his hair loss options, he reflected that he wished he had sought expert advice years earlier.
While individual outcomes vary, John’s experience highlights a common reality: many men live with uncertainty for years, assuming nothing can be done. Often, the most reassuring first step is simply gaining an accurate clinical diagnosis.

Frequently Asked Questions
Is male pattern baldness hereditary?
Yes. Genetic susceptibility plays a primary role and can be inherited from your mother’s, father’s, or both sides of the family; the patterning and rate at which the condition takes effect vary.
Can male pattern baldness start in your early twenties?
Yes, and before. The condition can begin anytime after puberty, making early twenties onset relatively common.
Does male pattern baldness always start with a receding hairline?
Some men experience temple recession first, while others notice diffuse thinning at the crown or top of the scalp.
Can stress look like male pattern baldness?
Stress causes temporary diffuse shedding (telogen effluvium), whereas male pattern baldness causes localised, progressive miniaturisation. Both can occur at the same time.
Can male pattern baldness come from my mother’s side?
Yes, also. The genetic predisposition can be passed down through either parent.
When should I see a trichologist?
You should schedule an assessment as soon as you notice persistent recession, crown thinning, or changes in hair density to establish an accurate diagnosis and understand your options.
