Drinking up to 400 milligrams of caffeine per day, as recommended by the Food and Drug Administration (FDA), isn't likely to create problems, but if you habitually drink more than 400 milligrams of caffeine per day, it may become problematic for your hair's health.
If you're a coffee drinker, you've probably wondered whether caffeine causes hair loss. In the past, it was believed that caffeine could accelerate hair loss. However, recent studies suggest that there's no link between caffeine and hair loss.
While having that cup of coffee a day can help to encourage healthy hair growth, also note that drinking too much can cause hair loss to occur as well. Consuming too much caffeine can stunt the growth of hair during the hair growth cycle. It can work to slow down this process, meaning your hair may not regrow quickly.
Making a coffee rinse at home is simple. Depending on the length of your hair, pour 2 to 4 cups of brewed coffee into a spray bottle. Make sure that it has cooled down completely before you do so. Spray the brewed coffee on your wet hair, making sure to saturate all your hair strands.
Coffee is rich in a whole lot of nutrients and vitamins that are good for your hair in more ways than one. Studies have shown that caffeine has the ability to stimulate and boost hair growth, reduce hair loss, and make hair thicker and longer.
Pour the cold coffee through your hair, starting at the roots, then gather all of your hair under a shower cap and let it sit for 20-60 minutes. Rinse your hair with warm water and allow your hair to air dry. You can repeat this treatment once a week.
Caffeine doesn't cause hair loss but it can prevent your hair from growing when consumed in excess. When it comes to the relationship between hair loss and coffee, the tannins in coffee are the problem, not caffeine.
It gives natural shine and luster to your tresses without damaging them. It darkens your hair color, thereby adding natural tint and enhancing the texture of your hair. It is a good scalp treatment. Coffee can be added to any hair pack, shampoo, or conditioner to increase its effectiveness.
The Relationship Between Caffeine and Your Hair
There's not a lot of scientific research on how caffeine affects human hair growth or hair loss. But the short and sweet news is that — as mentioned above — there's no firm evidence to suggest a link between caffeine and hair loss.
Amongst such signals are those sent to the hair follicle to promote cell proliferation and therefore – hair growth. With caffeine blocking this enzyme from blocking the signals, cells, specifically keratinocytes, can multiply which leads to thickening of the hair bulb and extension of anagen – growth stage.
Coffee is a pretty safe ingredient to be used in your DIY hair treatments. Just make sure to use organic coffee for best results, however, even instant coffee can deliver the desired results as well.
She adds that there are also caffeine-infused hair serums, which can be left on the scalp overnight for maximum absorption. Serums and scalp masks can be used one to two times per week. "Massaging the product into the scalp will further stimulate circulation and allow more of the ingredient to be absorbed," she says.
In addition to blocking DHT, caffeine is an effective anti-inflammatory.
Caffeine also encourages your hair to keep growing, kind of like how minoxidil—aka what's in popular treatments like Rogaine—does. So basically, think of caffeine haircare as a form of prevention and as a proactive way to get longer, thicker, healthier hair.
Coffee can be applied topically to the scalp and hair to reduce hair loss and encourage regrowth. Coffee's caffeine content can promote hair growth and halt hair loss. It stimulates the hair shafts, causing the roots of the hair to grow longer and wider. As a stimulant, caffeine promotes blood flow to hair follicles.
Coffee can help temporarily cover grey hair, all without the use of harsh store-bought chemicals. So, let's take a look at how coffee can help darken your hair while leaving your hair looking shiny and polished.
Caffeine is a mild stimulant that can stimulate blood circulation, and while it won't stop hair thinning or shedding on its own, it's frequently used in professional in-salon treatments, and there's some evidence that it speeds up the hair growth cycle.
An increase in hair loss may result from a health-related issue, such as alopecia, a nutrient deficiency, pregnancy, or medication use. Treatment will depend on the cause, but avoiding heat treatment and other lifestyle tips may help manage it.
Currently, there is no clinically viable evidence that caffeine shampoos have a long-lasting effect on male pattern baldness. This type of hair loss occurs in men who have a sensitivity to the hormone DHT (a form of testosterone), which causes the hair follicles in the scalp to weaken and shrink.
Your new coffee look is temporary and may fade after 1-2 weeks. To make it last longer, wash your hair less frequently or touch it up with a coffee rinse.
Dip your hair into the coffee and leave it there for several minutes. Lean over in front of the bowl and dip the sections of your grey hair that you'd like to color into the coffee. Once you've dipped your hair, stay in that position for at least 3 minutes to let the coffee color absorb.
Still not convinced? Further research by Dr. Tobias Fischer has even shown that caffeine speeds up the hair growth cycle and increases the length of hair from 33-40%*.
