Many people believe that there is a positive correlation between prenatal vitamins and hair growth.
However, this popular belief is not substantiated with adequate scientific evidence.
Nonetheless, taking prenatal vitamins can help reduce certain vitamin deficiencies, thereby improving hair growth and health.
Prenatal vitamins are primarily meant for pregnant women to provide necessary nutrients like iron, calcium, folic acid etc to mothers-to-be and their babies.
Nonetheless, you can take these prenatal vitamins temporarily because they basically work as multivitamins, though with greater amount of folic acid, iron and other such nutrients.
Intake of prenatal vitamins for the purpose of growing hair faster does not cause any serious side effects because they do not contain hormones or other such substances.
However, excess of certain fat soluble vitamins may give rise to problems like stomach upset or constipation. It can also cause headache, nausea, vomiting and other similar issues in certain cases.
So, you will have to be careful about deciding a suitable dosage. In fact, it is better to discuss doubts about dosage with your doctor because certain vitamins can prove to be harmful in case there are any chronic health problems.
Hence, you need not rely on prenatal vitamins if you already take a healthy and balanced diet rich in hair vitamins like vitamin B3, B5, B6, B7, B12, vitamin A, C, E iron, zinc, amino acids etc.
Prenatal vitamins are available in the form of tablets, gel capsules and liquids. It has been observed that pregnant women taking prenatal vitamins tend to have relatively higher rate of hair growth, thereby indicating positive effect of prenatal vitamins on hair growth.
However, this increase in hair growth can also be attributed to hormonal changes taking place during pregnancy.
Moreover, it is believed that the strands of hair going through the growth stage (anagen phase) of hair growth cycle are locked in that stage during pregnancy and this encourages them to grow longer throughout the pregnancy.
Therefore, there is need for further research in this regard to determine favorable how exactly do prenatal vitamins affect the rate of hair growth.
