How Genetics Impacts Hair loss

Scroll to read

While hair loss can be attributed to various factors, one significant influence that often determines its occurrence is genetics. Understanding the role of genetics in hair loss is essential if you are seeking to comprehend the root causes of your thinning hair and explore potential solutions.

This article will shed light on the relationship between our genes and precious locks. 


Male pattern hair loss

An estimated 30% to 50% of men develop male pattern hair loss by age 50. Male pattern hair loss, also known as male androgenetic alopecia, is the most prevalent form of hair loss for men. 

It is characterised by a pattern of hair thinning and balding that typically begins at the temples and the crown of the head. As the condition progresses, these areas of balding may merge, resulting in a distinct “M” shape hairline or a horseshoe pattern of hair remaining around the sides and back of the head.

One of the key factors contributing to male pattern hair loss is genetics. You may be more susceptible to experiencing this type of hair loss yourself if you have a family history of male pattern baldness. This genetic predisposition is closely linked to the influence of hormones, particularly dihydrotestosterone (DHT), a byproduct of testosterone.v

In men with a genetic predisposition to hair loss, DHT interacts with hair follicles on the scalp, causing them to shrink over time. The hair follicles become smaller, producing thinner and shorter strands until they eventually stop growing visible hair. The exact mechanism by which DHT affects hair follicles is complex, involving the sensitivity of hair follicles to DHT and the duration of the hair growth cycle.

Male pattern hair loss can begin in the late teens or early twenties. However, it can start later; some men may experience hair loss in their 40s or 50s. 


Female pattern hair loss

Unlike male pattern hair loss, where complete balding is apparent, female pattern hair loss typically leads to diffuse hair thinning on the top of the scalp. Women may notice a widening part line and decreased hair density, especially in the frontal and crown areas.

Like male pattern hair loss, genetics play a role in female hair loss. If you have a family history of female hair loss, you may have an increased risk of experiencing this condition. The genetic connection involves the influence of hormones, specifically the sensitivity of hair follicles to DHT.

DHT interacts with the hair follicles on the scalp, leading to a gradual shortening of the hair growth cycle. The hair follicles react by producing finer, thinner hair strands and reducing hair density over time.

Female pattern hair loss can start after puberty, but women typically first notice it in midlife, around their 40s or later.


Treatment options

While genetic factors contribute to hair loss, specific lifestyle changes and treatment options can help manage and improve the condition.


Healthy diet

A healthy diet of nutrients, vitamins and minerals can support male and female pattern hair loss management by promoting hair health and growth, nourishing the hair follicles and improving their overall condition.


Proper hair care

Good hair care involves gentle handling, using mild products, avoiding excessive heat styling, and balancing hydration. These practices promote a healthy scalp environment, minimise damage, and support overall hair health and growth.



Hair supplements can support male or female pattern hair loss by providing essential nutrients to nourish hair follicles and promote healthy hair growth.

However, tailored hair loss supplements like Nutrafol offer more effective hair loss and growth solutions. Nutrafol contains vital ingredients that target hair loss at the root. One of them is saw palmetto, which helps fight hair thinning by preventing the conversion of testosterone to DHT. Tocotrienol complex, on the other hand, lowers oxidative stress from the environment to improve hair density.

Choosing targeted supplements like Nutrafol is beneficial, as a one-size-fits-all approach may not work in addressing male and female pattern hair loss.


Hair transplantation

Hair transplantation is suitable for more significant hair loss. This surgical procedure is for you if you have apparent balding and thinning. It involves transplanting healthy hair follicles from the back of your scalp to balding or thinning areas, resulting in natural-looking hair growth.
