When addressing hair loss and restoration, treatments like PRP therapy, Minoxidil, or hair transplants are often the first to come to mind. However, there is another important but often overlooked factor—sleep. Could better sleep habits support hair regrowth, or is this idea simply another wellness myth?
At Vinci Hair Clinic, we believe in understanding the science behind hair health to provide comprehensive care. This guide examines the connection between sleep quality and hair growth, how poor sleep might contribute to hair thinning, and steps you can take for better overall scalp health.
How Does Hair Grow?
To understand the role of sleep in hair health, it’s useful to revisit the basics of the hair growth cycle, which consists of three phases:
- Anagen Phase (Growth): Lasting 2–7 years, this is when active growth takes place.
- Catagen Phase (Transition): A brief period of around 10 days during which the hair follicle begins to shrink.
- Telogen Phase (Resting/Shedding): A 3-month phase in which hair sheds and the follicle prepares for new growth.
Proper sleep supports the anagen phase, promoting active hair growth. Interrupted sleep cycles can prematurely trigger more follicles to enter the telogen phase, leading to telogen effluvium—a temporary yet noticeable increase in hair shedding often linked to stress or hormonal changes.
What Happens to Hair When You Don’t Sleep Well?
1. Higher Cortisol Levels
A lack of quality sleep can stimulate the production of cortisol, the stress hormone. Elevated cortisol levels encourage more hair follicles to enter the telogen phase prematurely, resulting in excessive hair shedding.
2. Reduced Nutrient Supply
During sleep, the body focuses on repairing and regenerating cells. Poor sleep disrupts blood circulation and reduces the delivery of oxygen and nutrients to hair follicles. These follicles, being highly sensitive, require proper nourishment to thrive.
3. Hormonal Imbalances
Sleep greatly influences hormone regulation, including melatonin, growth hormone, and oestrogen/testosterone. Disruptions in these hormones due to persistent sleep deprivation can lead to scalp-related issues and hair thinning.
What Does Research Say?
Scientific studies suggest the connection between sleep and hair health, although further investigation is required to solidify this link:
- Sleep deprivation is linked to oxidative stress, which can harm hair follicle cells.
- Melatonin, a hormone produced during sleep, has shown potential as a stimulant for hair growth. Studies even suggest the benefits of topical melatonin for conditions like androgenetic alopecia.
- Individuals with chronic insomnia frequently report increased hair shedding and slower regrowth.
Can Improved Sleep Enhance Hair Growth?
While improving your sleep won’t reverse genetic or advanced forms of hair loss, it can positively impact overall scalp health and may reduce shedding caused by stress or lifestyle factors.
For those undergoing treatments such as hair transplants, PRP therapy, or using Minoxidil, adequate sleep can create an ideal environment for healing and optimising results.
Sleep Hygiene Tips to Support Hair Health
Adopting better sleep habits can have a positive effect on your well-being, including hair health. Here are some simple measures to enhance your sleep quality:
- Aim for 7–9 Hours of Sleep: Maintain consistent sleep-and-wake schedules.
- Limit Screen Time Before Bed: Avoid exposure to blue light 1–2 hours before sleep to enable melatonin production.
- Manage Stress: Incorporate calming activities such as stretching, mindfulness, or journaling before bed.
- Avoid Late-night Heavy Meals: Eating large meals close to bedtime can disrupt sleep quality.
- Keep Your Bedroom Dark and Cool: These conditions support melatonin production, benefiting both sleep cycles and potentially promoting hair follicle function.
