Chances are, you’re familiar with the connection between sleep and skin health, and how a shortage of beauty rest can impact your overall appearance. Interestingly, recent studies show that a good night’s sleep is not only essential for overall well-being but also plays a crucial role in health hair.
Dr. Erin GILBERT, Board Certified Physican and Dermatologist, says “All structures of the body undergo cellular renewal while the body sleeps, most notably between [the hours of] 10pm and 3am, and “Younger and older people can often get away with less sleep, however those in the middle, particularly those entering the peri-menopausal stage in the mid to late thirties or forties, can really feel the effects of inadequate sleep.” Evans, Shalwah.

The Basics of Hair Growth:
To comprehend the connection between sleep and hair health, it’s essential to grasp the fundamentals of hair growth. Hair follicles undergo a cycle of growth, rest, and shedding. Quality sleep supports the growth phase, known as anagen, when the cells in the hair bulb rapidly divide.
Melatonin and Hair Pigmentation:
Melatonin, a hormone produced during sleep, not only regulates our sleep-wake cycle but also influences hair pigmentation. Studies suggest that a disrupted sleep pattern may lead to a decrease in melatonin production, potentially affecting the color of our hair.
Cortisol Levels and Hair Thinning:
A study by the National Center for Biotechnology Information found that lack of sleep can elevate cortisol levels, a stress hormone. Elevated cortisol is associated with hair thinning and loss. Moreover, if your system is stressed and your gut can’t absorb the nutrients you’re consuming. By prioritizing quality sleep, you can help maintain a balanced cortisol level and promote healthier, fuller hair.
Blood Flow and Nutrient Delivery:
During deep sleep, blood flow to the scalp increases. This enhanced blood circulation ensures that hair follicles receive a sufficient supply of nutrients and oxygen, contributing to optimal hair health.

Repair and Regeneration:
Sleep is a crucial time for the body to repair and regenerate cells, including those in the hair follicles. Adequate sleep supports the maintenance of a healthy scalp and hair structure, preventing issues like dryness and brittleness.
That being said, Gilbert explains that not getting enough sleep alone isn’t a reason to fear that your hair will fall out. There are several factors that can contribute to stunted hair growth or hair loss, but there are steps that you can take to find balance that promotes healthy hair. Evans, Shalwah.
