To the Root and Good Night Grey are the 24-hour haircare solution for thicker, longer hair

The 24-Hour Haircare Revolution: 2 Scalp Serums for Thicker, Longer Hair

BY JAY SMALL, TRICHOLOGIST, HAIRSTYLIST AND CO-FOUNDER OF AREY

When it comes to skincare, the idea of different morning and nighttime routines is well-established – protect during the day and repair at night. Most of us don’t pay much attention to our haircare beyond our regular wash-condition schedule, but if you’re serious about growing thicker, longer hair, with less grey hair growth, then a 24-hour haircare routine should definitely be on your radar.

Our philosophy behind Arey’s science-backed approach to hair growth and health is to support your hair day and night. To The Root® and Good Night, Grey™ are serums that work together to create a continuous cycle of protection, repair, and renewal, working in sync with your body’s natural rhythms to support scalp, follicle, and hair health from morning to night.

Why 24-Hour Haircare Matters

Your scalp is skin, and just like your face, your scalp needs protection from environmental stressors during the day and support when it goes into repair mode at night. Exposure to sunlight, pollution, oxidative stress, and hormonal fluctuations can all impact your hair growth cycle, pigment, and overall health. The result – slower hair growth, increased shedding, greying, thinning, and loss of density.

Rather than relying on a single product, we designed To The Root® and Good Night, Grey™ to be used together as a powerful combination of morning and nighttime treatments that deliver continuous support to your hair and scalp – in other words, a full “AM to PM” system.

The Arey 24-hour haircare system mirrors how skincare has evolved recognizing that what your skin needs in the morning is different from what it needs at night.

Here’s how To The Root® and Good Night, Grey™ work together to support your hair growth cycle and health around the clock:

 

Your Morning Defense: To The Root® Scalp Serum

Start each day right with To The Root® – a lightweight, oil-free scalp serum. To The Root® scalp serum is your first line of defense against environmental and biological stressors that your hair encounters throughout the day.

To The Root® is clinically formulated to:

    • Help slow the appearance of grey hair.

    • Support thicker, fuller hair growth.

    • Improve overall scalp health and balance.

    • Add volume without weighing hair down.

Consistent daily use can lead to visible improvements in hair growth and density, and reduced greying over time.

How To The Root® Scalp Serum Works:

During the day, your hair is exposed to UV rays and pollution that can trigger oxidative stress – an overproduction of unstable molecules (free radicals) that can damage healthy scalp and hair cells. Oxidative stress is one of the key contributors to premature greying and structural hair damage. To The Root® combats oxidative stress with a protective blend of peptides and antioxidants delivered where you need it the most – your hair roots. 

Because it’s oil-free and lightweight, To The Root® absorbs quickly and won’t leave you with unwanted bed head. Plus, you can use it on wet or dry hair.

 

Why Morning Application of To The Root® Matters:

Daytime is when most of your energy is targeted towards activity and less towards repair. It’s also when you are more likely to be outside in the sun or exposed to smoke, pollution, and stress – all of which are known triggers for hair-damaging oxidative stress. Using To The Root® in the morning can act as a protective layer, helping your scalp stay balanced and resilient throughout the day.

Nighttime Repair: Good Night, Grey™ Scalp Serum

While daytime care with To The Root® focuses on protection, nighttime is when your body focuses on repair – and that’s where Good Night, Grey™ scalp serum comes in. A good way to think of Good Night, Grey™ is as a “night cream for your scalp.”

Good Night, Grey™ is an overnight scalp serum specifically designed to:

    • Support hair follicle recovery during sleep.

    • Reduce stress-related damage to the scalp.

    • Promote melanin production.

    • Extend the hair growth phase.

Clinical ingredient studies have shown improvements in hair thickness and the overall health of your hair roots (follicles) when using Good Night, Grey™ at night. 

How Good Night, Grey™ Works:

Unlike daytime products, Good Night, Grey™ is formulated to work with your body’s circadian rhythm – the natural cycle that governs sleep, repair, and cellular renewal.

Good Night, Grey™ works with your body’s natural nighttime repair processes to:

    • Block cortisol (stress hormone) receptors that can contribute to hair aging.

    • Support melanocyte activity (cells responsible for hair pigment).

    • Neutralize oxidative stress from free radicals produced during the day.

When you get a good night’s sleep, you wake up feeling rested and restored. It’s the same for your hair and skin. Good Night, Grey™ is an easy way to give your body a helping hand.

Why Nighttime Application of Good Night, Grey™ Matters:

Nighttime is when your body shifts into restoration mode. As you sleep, stress hormones naturally lower, and your body prioritizes repair and healing. Your scalp, like your skin, also becomes more permeable, so it can absorb nourishing ingredients more easily. 

By applying Good Night, Grey™ before bed, you’re allowing the formula to:

    • Penetrate more effectively.

    • Work uninterrupted for several hours.

    • Target deeper biological processes.

If you want to boost hair growth even more, try massaging Good Night, Grey™ into your scalp with gentle circular motions, or use our Scalp Brush to help stimulate blood flow to your roots.

 

Two Scalp Serums Working Together for 24-Hour Haircare 

While each scalp serum is effective on its own, the real innovation lies in how To The Root® and Good Night, Grey™ work together to complement each other.

Together, the two scalp serums create a continuous cycle of care that mirrors your body’s natural rhythms. Using both products delivers 24-hour haircare that ensures the needs of your scalp and hair follicles are never left unaddressed.

 

Arey, the Clean Way to Build Your 24-Hour Haircare Routine

Sticking to a haircare routine is easier when you feel confident about the safety of the ingredients in your haircare products. That’s why Arey only uses clean ingredients and is always free from phthalates, parabens, artificial colors, and fragrance, and is also gluten-free, vegan, and cruelty-free. In fact, Arey is preferred by dermatologists more than any other anti-aging haircare brand.

You should see positive results in your hair color, thickness, and density after 2 months of consistent use, so we recommend setting up a subscription order to help keep you on track. Plus, you benefit from up to 25% off subscription orders.
