According to Marie Claire, hair can't technically grow faster than its natural growth rate. However, there are ways to facilitate hair growth, such as massaging the scalp to stimulate the follicles. Taking vitamins can help the hair grow at a healthy rate. B vitamins make the hair stronger, and deficiencies in vitamins, particularly biotin, can slow hair growth.
Biotin can prevent shedding and prompt the hair to grow about 1/4 inch each month, according to Style List. A healthy diet also facilitates hair growth. Foods that are rich in protein, such as whey and lean meat, help to make hair healthier. Vitamin A is essential for healthy hair as well; this vitamin is found in foods such as eggs and kale. Eliminating stress can also result in healthy hair growth. Stress can cause hair to fall out in unhealthy amounts. Reducing heat-styling is another way to ensure hair is able to grow at a healthy, natural rate. Heat-styling can cause breakage, which decreases volume and stunts hair growth. Trimming the hair often to remove split ends contributes to healthy hair growth. Avoiding putting unnecessary stress on the hair follicles, such as tight pony-tails, braids or restrictive styles, can contribute to hair healthiness.
Massaging your scalp with castor oil, olive oil or jojoba oil may also encourage hair growth by improving your scalp's health. Apply the oil to your scalp, and then massage it in a gentle, circular motion for three to five minutes before shampooing it away.
