Dry January: How Cutting Alcohol Can Boost Your Hair Health
8 Jan 2026
Dry January = Better Hair Growth Conditions
Every January, millions of people commit to a Dry January – taking a month off alcohol to reset their bodies and minds. While the mental and physical benefits are well-documented, fewer people realise this reset can also benefit your hair.
Alcohol impacts hair health in several ways:
Sleep disruption – poor sleep impairs hair follicle recovery
Nutrient depletion – alcohol can reduce absorption of biotin, zinc, iron and vitamin D, all essential for hair growth
Worsening inflammation in skin and scalp conditions – excess alcohol increases oxidative stress and scalp inflammation, which can lead to hair loss
By choosing a Dry January, you’re giving your hair the ideal conditions to thrive. Think of it as a reset for your scalp – healthier follicles, improved growth cycles and a chance to truly nourish your hair from the inside out.
Why Hydration Matters in January
Ironically, the cold, dry winter air and indoor heating in January can dehydrate hair, leaving it brittle and dull – even if you’re avoiding alcohol.
To make the most of your Dry January for hair growth, it’s essential to keep your hair and scalp hydrated.
1. Keep Your Scalp Nourished
A healthy scalp = a healthy foundation for hair growth.
Tips:
Use a gentle, hydrating shampoo 2–3 times per week. Over-washing can strip natural oils.
Incorporate a conditioner or scalp-focused leave-in treatment to maintain moisture.
Try weekly scalp massages to increase blood flow.
2. Hydrate From the Inside Out
Alcohol can dehydrate your body and even when abstaining, winter can still make your hair prone to dryness.
Tips:
Drink at least 1.5–2 litres of water daily.
Eat water-rich foods like cucumber, celery, oranges and berries.
Include healthy fats (e.g. avocados, nuts, seeds) to help maintain hair moisture and shine.
3. Protect Hair from Environmental Dryness
Cold air, indoor heating and harsh styling can make winter hair brittle.
Tips:
Use a microfiber towel or cotton T-shirt to gently dry hair.
Avoid hot styling tools daily; use heat protectant sprays when you do.
Sleep on a silk pillowcase to reduce friction and moisture loss.
4. Pair Dry January with Your Hair Regrowth Routine
The best time to see results from prescription treatments is when your hair and scalp are healthy.
Prescription treatment: Consistent use stimulates hair follicles and hair growth.
Supplements: Ensure you’re supporting hair from within with nutrients like biotin, zinc, iron, vitamin D and omega-3s.
Healthy habits: Sleep well, stay hydrated and minimise stress where possible.
Think of Dry January as a reset button: with alcohol out of the picture and your scalp hydrated, your treatment can work at its full potential.
5. The Not-So-Dry January Challenge
Make January a month of hydration and regrowth:
Skip alcohol and commit to your hair-healthy routine.
Track your progress with photos and journal entries.
Focus on scalp care and hydration daily.
Pair your routine with supplements and prescription treatment.
Even small changes compound over the month – prepare your hair to grow
The Bottom Line
Dry January isn’t just good for your body and mind – it’s also great for your hair. By cutting alcohol, prioritising hydration and supporting your scalp with the right routines and treatments, you create the ideal conditions for regrowth and healthy strands.
A hydrated scalp, strong follicles and consistent treatment are the perfect combo for visible progress in 2026.
Dry January = hydrated scalp + better hair growth. Start your month strong – your hair will thank you.
