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.
The short answer is - No, it's not true! Caffeine does not cause hair loss when applied on the scalp but here's what's important – it must be used in moderation.
Caffeine may offer several benefits for hair, including: suppressing the hair loss hormone DHT. stimulating hair growth. encouraging elongation of the hair shaft.
Your hair growth may slow down.
If you're trying to grow your hair faster, having a cup of coffee a day can actually help you get longer strands. Caffeine targets dihydrotestosterone — a hormone that may cause hair loss.
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.
In alopecia areata, the immune system mistakenly attacks hair follicles, causing inflammation. Researchers do not fully understand what causes the immune attack on hair follicles, but they believe that both genetic and environmental (non-genetic) factors play a role.
For healthy adults, the FDA has cited 400 milligrams a day—that's about four or five cups of coffee—as an amount not generally associated with dangerous, negative effects.
Up to 400 milligrams (mg) of caffeine a day appears to be safe for most healthy adults. That's roughly the amount of caffeine in four cups of brewed coffee, 10 cans of cola or two "energy shot" drinks.
Caffeine and hair growth
We would need an equivalent of 50-60 cups of coffee in order to produce noticeable hair-growing results – the amount which is unsafe and dangerous for your health, and is NOT what you should do.
Caffeine doesn't cause hair loss but it can prevent your hair from growing when consumed in excess.
Hair follicle damage occurs gradually, eventually leading to baldness. But according to research, the caffeine in coffee can help stimulate hair growth and stop hair loss. One 2007 laboratory study found that caffeine helped block the effects of DHT in male hair follicles.
“Coffee can cause insomnia, nervousness, restlessness, upset stomach, nausea, and vomiting, increased heart rate and breathing rate, and other side effects,” Rissetto says. “Consuming large amounts of coffee might also cause headache, anxiety, agitation, ringing in the ears, and irregular heartbeat.”
Too much caffeine can also cause anxiety in people with panic or anxiety disorders. For those who drink coffee, experts suggest brewing it with a paper filter, because unfiltered coffee is associated with higher rates of early death, and can contain compounds that raise levels of LDL, or “bad,” cholesterol.
But as with any good thing, too much coffee—too much caffeine specifically—is a bad thing. Too much caffeine can cause high blood pressure, a precursor to heart disease, and can cause side effects like dizziness, shakiness, headache, or abnormal heartbeat.
So how much coffee is the optimal amount to drink to get all the benefits, but avoid the negative side effects? According to the Dietary Guidelines for Americans, it's safe for most women to drink three to five cups of coffee a day with a maximum intake of 400 milligrams of caffeine.
Coffee still has potential risks, mostly due to its high caffeine content. For example, it can temporarily raise blood pressure. Women who are pregnant, trying to become pregnant or breastfeeding need to be cautious about caffeine.
Drink it black
The healthiest way to drink coffee is plain with nothing added — also known as drinking it black. Dr. Hashmi explains, “Ideally, you shouldn't put sugar in your coffee.
The first sign of alopecia areata is often a round or oval bald patch on the scalp.
The three most common triggers for hair loss in young women are stress, dieting, and hormonal changes. Less commonly, hair loss can be caused by certain autoimmune diseases. Here's more on these four triggers for hair loss in young women.
The condition can develop at any age, although most people develop alopecia areata for the first time before the age of 30. Alopecia areata is not life-threatening and does not cause physical pain.
Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss.
Lifestyle factors could include using certain hair products, wearing your hair up too tightly, experiencing high stress levels, or not getting enough of certain vitamins and minerals in your diet. People who have immune system deficiencies could also have thinning hair.
