Health Risks Because it also contributes to cellular aging, it can cause early wrinkles, gray hair, and hair loss. One of the more well-known effects of caffeine is getting a good night's rest. Many people are careful not to drink caffeine in the afternoon so it won't keep them awake at bedtime.
Coffee acts as one of the safe ingredients for dyeing your grey hair naturally without compromising its quality.
There is no scientific evidence that drinking coffee causes white hair. The color of hair is determined by the presence of melanin, which is produced by cells called melanocytes. As we age, the production of melanin decreases, leading to the appearance of gray or white hair.
Amla enriches hair pigmentation. Dried fruit of amla and coconut oil can be boiled together till it gets charred and used to prevent hair greying. You can massage your hair with this amla oil and drink amla juice regularly to avoid premature greying of hair.
Using coffee for hair, helps stimulate your hair follicles and speeds up hair growth. Caffeine also improves the blood circulation to your scalp, which in turn allows for nutrients to reach your scalp more efficiently. This results in a quicker and healthier hair growth.
"Ensure you have an adequate level of Vitamin D3 and Vitamin B12, since deficiencies in either of these may accelerate graying," explains Lain. Other important micronutrients for healthy hair include vitamin E, vitamin A, zinc, iron, copper, selenium and magnesium.
Vitamin A, C and B12 are the most needed vitamins to increase the melanin production in your hair. Add citrus fruits like oranges, grapes, pineapple, and melon to your diet. Also eat vegetables like potatoes, carrots, beans, etc. Non vegetarians can try adding red meat, chicken liver, fish, and eggs to their diet.
Coffee is a super versatile and incredibly effective all-natural beauty ingredient. Dying your hair with coffee is a great way to achieve that classic dark shade of brown. It is a natural, safer, and cheaper alternative for hair colouring that only requires one ingredient: coffee! And voila, you're done.
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.
Green tea cannot reverse the greying of hair. However, it can delay the process because of its antioxidant property. Free radical damage may be the reason for greying of hair. By scavenging those free radicals, green tea can slow down the process.
Caffeine on the brain
Their results — which were based on a neuroimaging study and published in the journal Cerebral Cortex — show that, indeed, coffee temporarily reduces gray matter volume. Surprisingly, though, this was not associated with disrupted sleep.
It's not possible to reverse or treat gray hair.
Premature graying may be reversed with vitamin B12 supplementation only if vitamin B12 deficiency is the cause. If you are graying due to other factors, such as genetics, zinc deficiency, and medications, your gray hair cannot be reversed.
Typically, white people start going gray in their mid-30s, Asians in their late 30s, and Blacks in their mid-40s. Half of all people have a significant amount of gray hair by the time they turn 50.
If you want to get darker hair and prevent gray hair completely, use coffee on regular basis. Simply take one cup of coffee and mix it with one cup of water. You can also add 2-3 spoons of coffee powder and allow it to dissolve. Let the coffee powder dissolve completely and then apply on your hair.
It encourages hair growth and fights hair loss
According to the NCBI study, DHT makes hair follicles shrink. And since coffee can oppose this action while also stimulating hair follicles, it also promotes faster hair growth and prevents hair loss.
While vitamins cannot reverse gray hair, they can slow down the process. Eating a diet rich in vitamins D, B5, and B12, iron, and calcium can prevent your existing hair from turning gray.
Dairy and dairy products like curd and cheese are rich in vitamin B12. Since vitamin B12 is essential for making DNA, which is the genetic material found in all cells of the body including hair follicles, a deficiency of it can lead to under-nourishment of hair leading to premature greying.
