The UK beauty industry generated a revenue of $1.89bn in 2024 and is projected to grow annually at a rate of 1.24% according to Statista.
When it comes to hair loss in particular, stats by Medihair suggest that around 85% of men and 33% of women will at some time face hair loss. It’s no surprise then that the tech world has rallied to help people combat hair loss and improve hair growth.
What Stops Hair Growing?
There are a number of reasons that hair might stop growing. Whilst some of these will be genetic – which can’t be changed through technology – other lifestyle factors may be helped. Some of these include:
Hormones: Hormones like testosterone can have an impact on hair growth in men. Likewise, hormonal shifts due to pregnancy, menopause, thyroid issues or conditions like polycystic ovary syndrome (PCOS) can also have an effect on hair growth in women. Tech and startups that help manage these imbalances could improve hair growth.
Nutrient deficiencies: Lack of nutrients, especially iron, vitamin D, biotin, and protein can affect hair growth. Hair cells need these nutrients to grow, so any deficiencies can slow the process. Startups that help people identify these could help them improve hair growth on a nutrient level.
Bad Hair Care: Using too much heat or chemicals on hair can stop it growing. Tech companies that focus on heat-less styling can help combat this by preventing damage in hair.
Lifestyle: Smoking, a bad diet and lack of sleep can also affect hair growth. When general health is poor, the whole body is affected – including hair. Tech that help people monitor their health can help remove any risks that might prevent hair growth.
How Is Tech Helping With Hair Growth?
When it comes to tech devices for hair growth, these fall into a few categories:
Hair transplant technology – Hair transplant technology has become hugely popular in recent years for those suffering with hair loss. These technologies remove follicles and replant them in ‘thin’ areas, stimulating thicker hair growth.
Hair scanners – Starting in Asia but heading west, hair scanners are able to identify hair health and treat it. For example, those with dry or oily scalps can get personalised treatment plans based on their scalp composition – helping their hair grow faster.

Lasers therapy – Handheld devices that emit laser light can help stimulate hair follicles and encourage more growth. These devices improve blood flow to the scalp to help improve growth.
Low-heat styling devices – One of the main culprits of bad hair growth is heat damage. New devices by haircare giants like GHD and Dyson are helping people style their hair whilst reducing damage.
Genetic testing – Genetics can play a huge role in hair loss, and knowing if you are pre-disposed to this can help combat it early. At home genetic testing kits are becoming much more popular, allowing people to make informed decisions about their hair care.
