The amount of biotin suggested for hair growth usually ranges between 100 - 1,000 micrograms (mcg) daily, but this number varies based on your body's reaction to biotin.
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.
Current recommendations for biotin by the Institute of Medicine state that the daily adequate intake (AI) for adults is 30 μg/day [1]. Most healthy individuals meet these requirements through a well-balanced diet, though many still take up to 500–1,000 μg of biotin supplementation daily.
Biotin is generally safe even at high dosages. Side effects of biotin are minimal and easily reversed because excess biotin is easily passed by the body through urine. We recommend taking 500 mcg-5,000 mcg of biotin per day to support healthy hair, skin, and nails.
Is biotin 10000 mcg good for hair growth? Yes, it works by stimulating the production of keratin. Keratin is a type of tough protein which is a building block of many parts of the body, including your hair. Did you know that about 95% of your hair is made up of this protein?
The normal recommended biotin dosage for adults is 30 to 100 micrograms (mcg) per day. But there's no evidence of high levels of biotin being harmful or causing toxicity, which is why you'll commonly see biotin supplements containing 5,000 to 10,000 mcg.

Regular intake of excessive quantities of certain nutrients can cause hair loss in some cases due to a temporary condition known as Telogen Effluvium. However, the effects of too much vitamin B7 - also known as biotin toxicity - remain unconfirmed.

Talk to your healthcare provider if you think you've taken too much biotin. You can also contact Poison Control if you're having trouble reaching your provider.
Biotin is a common component of multivitamin preparations and at high doses it has been reported to cause interference in immunoassays resulting in abnormal thyroid function tests [2].
We observed that long-term administration of biotin decreased systolic blood pressure in the SHRSP strain; also, a single dose of biotin immediately decreased systolic blood pressure in this strain.
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.
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.
Absolutely not, even though biotin supports hair growth, stopping the treatment cannot in any way speed up or trigger hair loss in any way.

Anticonvulsant Medications -- Long-term use of anticonvulsant medications can reduce the body's stores of biotin. Valproic acid can cause biotinidase deficiency, which may be helped by biotin supplements. Anticonvulsant medications include: Carbamazepine (Carbatrol)
