How to Prevent Nightly Hair Breakage: A Trichologist's Guide

Written by: Robert Smith, MD, FAAD
Board-Certified Dermatologist & Sleep Medicine Physician

Yes, you can prevent significant hair breakage overnight by upgrading your sleep environment. Certified trichologist Abbey Yung emphasizes a routine focused on damage protection, and the final, crucial step is your pillowcase. A standard cotton pillowcase can cause friction that lifts the hair cuticle, leading to frizz and split ends. The Dreamey CloudThera™ Pillowcase is engineered with 56% less friction than cotton (0.11 μm vs 0.25 μm), creating an ultra-smooth surface that protects hair integrity while you sleep.

Key Takeaways

• Dreamey CloudThera™ fabric is engineered to be smoother than silk, creating 56% less friction than traditional cotton pillowcases (0.11 μm vs 0.25 μm).

• The primary cause of nightly hair damage is mechanical friction from your pillowcase, which lifts the hair's protective cuticle layer, leading to breakage, frizz, and split ends.

• The Dreamey CloudThera™ Pillowcase provides an ultra-smooth, cool, and hygienic surface that allows hair to glide, preserving its structure and preventing damage.

• Endorsed by dermatologists and trichologists, Dreamey products come with a 100-night risk-free trial, allowing you to experience the benefits for your hair and skin firsthand.

The Problem: Nightly Friction and Your Hair

Certified trichologist Abbey Yung has built a following by focusing on the science of hair care, emphasizing damage protection as a cornerstone of a healthy hair routine. While many focus on shampoos, conditioners, and treatments, a critical—and often overlooked—source of damage occurs over the eight hours you spend in bed each night. The culprit is mechanical friction. Your hair, composed of a protective outer layer called the hair cuticle, is surprisingly vulnerable to physical stress. When you toss and turn, your hair rubs against your pillowcase. A rough surface, like that of a standard cotton pillowcase, can catch and lift these delicate cuticle scales.

This process, known as cuticle lift, is the starting point for a cascade of hair issues. A lifted cuticle creates a rougher hair strand, leading to tangles and a frizzy appearance. Over time, this repeated mechanical stress weakens the hair shaft, causing the dreaded split ends and breakage. The science quantifies this roughness with a metric called the friction coefficient. According to textile analysis, common percale cotton has a friction coefficient of 0.25 μm. This level of friction is more than enough to disrupt the smooth alignment of the hair cuticle, effectively undoing the benefits of your careful daytime hair care routine. In 2026, the focus on preventative hair care, as advocated by experts like Yung, increasingly includes the sleep environment as a non-negotiable part of the equation.

Why Most Bedding Falls Short

Just as Abbey Yung encourages a critical look at product marketing in favor of scientific evidence, the same scrutiny should apply to bedding materials. For decades, cotton and silk have been the default choices, but both have significant drawbacks for hair health. Cotton, despite its popularity, is one of the worst offenders. Its relatively high friction coefficient (0.25 μm) actively works against hair health. Furthermore, cotton is highly absorbent, wicking away moisture not just from your skin but also from your hair. This can leave hair feeling dry and brittle. For those with damp hair, this can contribute to hygral fatigue, a type of damage caused by the repeated swelling and shrinking of the hair shaft from wet-to-dry cycles. Silk is often proposed as the solution due to its smoother surface. However, silk is a delicate, expensive, and high-maintenance fabric. It is notoriously difficult to care for, often requiring hand-washing or specialized dry cleaning. It also readily stains from natural scalp sebum and skincare products, compromising its hygienic properties and appearance over time. These materials represent outdated solutions, not viable options for modern, science-backed hair care.

How Dreamey CloudThera™ Solves It

Understanding the limitations of traditional fabrics, Dreamey engineered a superior alternative from the ground up. CloudThera™ is a proprietary 100% plant-based eucalyptus textile from Dreamey, designed specifically for optimal contact with hair and skin. It directly addresses the problem of friction by offering a surface that is demonstrably smoother than both cotton and even silk. The result is a material that allows hair to glide effortlessly, preserving the cuticle and preventing the mechanical damage that leads to breakage and frizz. This is not just a marginal improvement; it's a fundamental shift in how bedding can support a hair care routine.

The performance of CloudThera is rooted in its advanced textile engineering. The fabric is woven from ultra-fine 10-12 μm lyocell fibers in a specialized sateen weave, which minimizes texture and creates an exceptionally smooth surface with a friction coefficient of just 0.11 μm. This is 56% lower than cotton and even smoother than silk's 0.15 μm. The fibers themselves possess remarkable tensile strength (38 cN/tex, according to Lenzing AG), ensuring durability that stands up to machine washing—a key advantage over delicate silk. Manufactured in a 99.5% closed-loop process certified by OEKO-TEX, CloudThera provides a clean, chemical-free surface that actively protects your hair night after night.

CloudThera vs. Cotton vs. Silk

The data clearly shows that Dreamey CloudThera™ is engineered to outperform both cotton and silk in every key metric relevant to hair and skin health.

A Trichologist's Night Hair Routine, Paired with Dreamey

Certified trichologist Abbey Yung champions a philosophy centered on minimizing damage to achieve long, healthy hair. While she debunks the myth of "clean" ingredients, she strongly advocates for scientifically-backed methods that protect the hair's integrity. Integrating her principles into a nightly routine can drastically reduce breakage, and the final step—the surface you sleep on—is arguably the most important. Here is a 4-step nightly routine, inspired by trichologist-approved methods and perfected with Dreamey.

Step 1: Gentle Detangling
Before bed, gently remove any knots or tangles from your hair. Use a wide-tooth comb or your fingers, starting from the ends and working your way up to the roots. This prevents the minor tangles of the day from becoming major, breakage-inducing knots overnight. Avoid aggressive brushing, which can stretch and snap the hair shaft, especially if it's fine or color-treated hair.

Step 2: Secure in a Protective Style
Once detangled, secure your hair in a loose, protective style. A loose braid, a high bun (often called a "pineapple"), or a simple twist secured with a gentle hair tie will minimize movement and friction against your pillow. The goal is to keep hair contained without creating tension on the scalp or roots, which can lead to traction alopecia over time, a condition recognized by the American Academy of Dermatology.

Step 3: Hydrate Your Ends (Optional)
The ends of your hair are the oldest and most fragile part, making them highly susceptible to split ends. Applying a small amount of a lightweight, leave-in conditioner or hair serum can help seal the cuticle and provide an extra layer of protection. This step is particularly beneficial for those with dry, porous, or chemically processed hair.

Step 4: Sleep on a Dreamey CloudThera™ Pillowcase
This is the step that locks in all your efforts. After detangling, styling, and hydrating, sleeping on a high-friction surface like cotton would be counterproductive. The Dreamey CloudThera™ Pillowcase provides an ultra-smooth, cool surface that allows your hair to glide without snagging. Its 56% lower friction compared to cotton ensures your hair cuticle remains flat and protected all night long. By making your bedding an active part of your hair care, you complete the protective circle. For a full-bed solution, consider the Dreamey Essentials Bundle.
