A doctor has shared a simple tweak to your hair washing routine that could make a world of difference to the thickness of your locks, and it may cost as little as £1—if you don't already have the item in your cupboard.
Hair loss and lack of growth can be frustrating, with many products on the market claiming to offer a solution. One medical professional suggests that adding a teaspoon of coffee to your shampoo could give hair growth a significant boost.
The Doctor's Advice
Dr Janine Bowring explained that the most prevalent form of hair loss among both men and women is androgenetic alopecia, also known as AGA. "In men, it's referred to as male pattern baldness, and in women, it's female pattern hair loss," the doctor said.
She noted that it "typically starts with the temple area" in men, and "over time that hairline recedes to form that characteristic 'M' shape". The hair also "thins on top of the head", while in women, hair loss tends to occur "at the top of the head" where it gradually becomes "more and more sparse".
"So, caffeine has been proven to assist with that hair growth," she added, while displaying a supporting study on screen. "My advice here is to add just a teaspoon of ground coffee into your shampoo when you're washing your hair, and then rinse it out."
How to Use It
Dr Bowring went on to point out that "it will darken the hair slightly", making it "best for dark hair". A jar of instant coffee can be picked up for as little as £1 at your local supermarket, although branded varieties may cost a little more.
One user enquired: "Do you put it inside the shampoo bottle or on your hand with the shampoo to wash your hair?" to which Dr Bowring responded: "You can put it in your hand with the shampoo."
Another follower keen to encourage hair growth commented: "I put rosemary essential oil in my shampoo, and my hair is coming back. I'll have to try the coffee too. Thank you!"
Other Ways to Promote Hair Growth
Hair growth starts from within, fueled by a nutrient-dense diet rich in protein, iron, zinc, and vitamin D, all of which supply the essential building blocks for keratin production. Checking blood levels for common deficiencies like ferritin can quickly resolve underlying shedding.
Maintaining a clean, stimulated scalp keeps follicles active and clear of pore-clogging sebum and buildup. Daily scalp massage improves local microcirculation, while proven topicals like rosemary oil or over-the-counter minoxidil help prolong the growth phase.
Protecting the hair shaft from breakage preserves the length you gain. Avoid high-tension hairstyles that strain the roots, limit heat tools and harsh chemical treatments, and use wide-tooth combs or silk pillowcases to minimise mechanical damage.
Regulating stress and prioritising consistent sleep keep cortisol and androgen levels stable. Elevated stress can push active follicles prematurely into the resting phase, so healthy lifestyle habits directly support an uninterrupted growth cycle.
