Hair loss can be caused by a variety of factors, from genetics to stress. One potential cause that is sometimes overlooked is lack of sleep. In this article, we'll explore the connection between sleep deprivation and hair loss, and provide tips for getting better sleep to promote healthy hair growth.
Can lack of sleep cause hair loss?
Yes, lack of sleep can contribute to hair loss. Research has found that sleep deprivation can disrupt the normal hair growth cycle and lead to excessive shedding and thinning of hair. Some of the ways poor sleep quality can impact hair health include:
- Increased stress hormone (cortisol) levels - High cortisol from sleep deprivation negatively impacts hair follicles.
- Nutrient deficiency - Lack of sleep can affect absorption of important hair-healthy nutrients like protein, iron, and zinc.
- Reduced growth hormone production - Growth hormone repairs hair follicles but is reduced with insufficient sleep.
- Inflammation - Sleep deprivation leads to systemic inflammation including the scalp, impeding healthy hair growth.
- Higher DHT levels - DHT is a hormone linked to pattern baldness. Lack of sleep increases DHT.
In essence, prolonged or severe lack of sleep throws off the body's hormonal balance and deprives the body of vital nutrients needed for robust hair growth. Getting insufficient or poor quality sleep leads to more hair falling out and slower regrowth.
How much sleep do you need for healthy hair?
The recommended amount of sleep for most healthy adults is 7-9 hours per night. However, some people may need a bit more or less sleep than this general guideline. The key is getting uninterrupted, high-quality sleep so you wake up feeling rested and refreshed.
Aim to get enough sleep to meet your body's needs for sustained energy, good mood, and optimal health - including your hair. If you have symptoms like constant fatigue, irritability, lack of concentration, and dark under-eye circles, your body is likely telling you that you need more sleep.
Tips for better sleep to support hair health
If you're dealing with hair loss, focus on improving sleep quality and duration. Here are some tips for getting enough high-quality sleep to promote healthy hair growth:
- Stick to a consistent sleep schedule - go to bed and wake up at the same times daily.
- Develop a relaxing pre-bedtime routine - take a bath, read, stretch.
- Wind down electronics use in the evenings.
- Avoid caffeine, large meals, and strenuous exercise close to bedtime.
- Sleep in a cool, completely dark, quiet room.
- Invest in a comfortable mattress and pillows.
- Manage stress through yoga, meditation, therapy.
- Try natural sleep aids like magnesium, chamomile tea, CBD.
- See your doctor if you suspect a sleep disorder.
Other benefits of adequate sleep
Getting enough quality sleep doesn't just promote healthy hair. It provides many other benefits including:
- Boosted immunity
- Improved memory and cognition
- Better mood regulation
- Increased energy and productivity
- Reduced inflammation
- Healthy weight maintenance
- Enhanced athletic performance
- Lowered risk for chronic diseases
Prioritizing sleep can quite literally help you look and feel your best while reducing risk of various health problems. Pay attention to how much restful sleep you get each night. If you have ongoing issues with sleep quality or duration, speak to your doctor to identify and address any underlying causes.

The bottom line
Lack of sleep can definitely contribute to hair loss in both men and women. Insufficient sleep disrupts hormone levels and deprives the body of vital nutrients necessary for healthy hair growth. To support lush, full hair, adults should aim for 7-9 hours of quality sleep per night. Improving sleep hygiene by sticking to consistent bedtimes, reducing screen time in the evening, and managing stress can help optimize sleep.
Getting adequate deep, restorative sleep is crucial for stimulating hair growth and stopping excessive hair shedding or thinning associated with sleep deprivation. Along with proper nutrition, stress management, and other healthy hair care practices, quality sleep promotes strong, vibrant hair growth.
