It takes months to see results on biotin. According to The Journal of Clinical and Aesthetic Dermatology (source), biotin takes around 90 days to begin to work. Contrary to some of the claims you may have heard, biotin is not an overnight remedy that will magically give you 5 inches of hair growth in 24 hours.
Most of the websites touting biotin for hair growth recommend taking 2-5 milligrams (2,000-5,000 mcg) of biotin in supplement form each day, and many supplements are sold under the name Biotin 5000, indicating a 5000 mcg (5 mg) size.
When taken by mouth: Biotin is likely safe for most people when taken in doses up to 300 mg daily for up to 6 months.
Biotin, also known as vitamin B7, stimulates keratin production in hair and can increase the rate of follicle growth.
Strengthens and thickens: Biotin "is well known for its positive effects on hair including growing stronger thicker strands," says Friese. Protects: Because biotin strengthens hair, it is less likely to break off at the ends, promoting and protecting length, explains Friese.
Does biotin cause weight gain? No, there is no evidence to suggest taking biotin supplements can lead to weight gain. In fact, biotin is sometimes touted as a weight-loss supplement. However, there is no research to confirm biotin has any effect on weight.
Research also shows that biotin helps improve skin's hydration, smoothness, and appearance. In addition, some studies show that biotin can strengthen fingernails and make them grow faster. Biotin is a versatile addition to your beauty routine.
The bottom line. There's no strong evidence to support using biotin for hair growth or to prevent hair loss in people without a deficiency. Because hair thinning and poor hair growth are sometimes associated with a biotin deficiency, correcting a deficiency can help restore hair growth in some people.
“We find biotin to be very helpful for hair disorders,” says dermatologist Wilma Bergfeld, MD. “It also makes nails thicker, and oral biotin is exceedingly safe, even in large doses.” It's primarily used for alopecia, the medical word for hair loss in men or women.
The best time to take biotin is in the morning, with a full glass of water. Biotin is best taken on an empty stomach 1 hour before eating or 2 hours after your last meal. You should aim to take biotin at the same time each day to stay on track.
A biotin deficiency can often reveal itself in weak facial hair growth or patchy beard growth. Although Biotin is often touted as a wonder hair supplement, but too high a dosage of Biotin can lead to acne, incensed sugar levels, slower release of insulin and skin reactions.
So which supports hair growth more: collagen or biotin? Based on scientific studies, it seems that collagen has a better claim to improving the condition of your hair. However, both can actually be used together for well-rounded nutrition and countless health benefits, aside from promoting hair regrowth.
The American Academy of Dermatology says that hair grows about 1/2 inch per month on average. That's a grand total of about 6 inches per year for the hair on your head. How fast your hair grows will depend on your: age.
Takeaway. Your body makes enough biotin on its own through your dietary intake each day. Therefore, you shouldn't take biotin supplements unless directed by your doctor. There are some rare health conditions that can cause some people to need biotin supplements on a regular basis.
Yes, they could. “Just like a skin supplement wouldn't just target your face, hair-growth supplements are going to affect all hair follicles, whether on your head, face, or legs,” Crysler says. The bright side is, if you don't already have facial hair, these supplements won't cause you to sprout some.
Mayo Clinic states that 10,000 mcg is a safe dose, as no adverse side effects have been noted to date. Reassuringly, even “mega doses” of 300,000 mcg found no side effects in neurological research.
Biotin supplements and acne
Currently, there is minimal evidence that taking biotin supplements causes acne. The logic behind such claims has more to do with pantothenic acid, or vitamin B5, than with biotin.
There is some evidence that biotin may help improve comedonal acne, which is acne that causes blackheads and whiteheads. It may also help control the flaking and irritation that occurs when you take retinoids for acne.
Hair Vitamins for Black Women
Some of the best hair vitamins for black hair growth and for the growth of other hair types are Biotin (Vitamin B7), Vitamin C and Niacin (Vitamin B3). Two of the best minerals for healthy hair growth are Iron and Zinc.
Most hair strands grow at an average rate of about 0.3 to 0.4 mm a day. So, this means it may grow up to one-tenth of an inch or a little more in a week. However, this growth differs with people. Genetics, hormones, nutrition, and stress levels all play a role when it comes to the health and growth of tresses.
Your hair grows 2 to 4 inches in 4 months, 4 to 6 inches in 9 months, and 6 to 8 inches in a year. Though this is how the usual growth cycle works, it also depends on seasonal changes, hair and scalp health, medications, hormonal changes, and diet among other factors.
1) Can biotin make my body hair grow out too? A. A common misconception about biotin, or any hair growth supplement, is that they can make your body hair grow out as well. This is not true since the hair follicles on your body do not follow the same rules as your scalp.
