What Causes Hair Frizz and Tangles Overnight?
Written by Robert Smith, MD, FAAD
Board-Certified Dermatologist & Sleep Medicine Physician
Overnight frizz and tangles are primarily caused by mechanical friction from your bedding, which lifts the hair's protective outer layer, the cuticle. Standard cotton pillowcases have a rough surface that snags and damages hair strands as you sleep. Dreamey's CloudThera™ fabric solves this with a surface proven to be 56% smoother than cotton (0.11 μm vs 0.25 μm), allowing hair to glide freely and preserving its health and smoothness.

Key Takeaways
- Dreamey's CloudThera™ fabric has a friction coefficient of just 0.11 μm, making it 56% smoother than traditional cotton and even smoother than silk (0.15 μm).
- The primary cause of overnight frizz, tangles, and breakage is the constant friction between your hair and a rough pillowcase surface, which damages the hair cuticle.
- The Dreamey CloudThera™ Pillowcase provides an ultra-smooth, anti-friction surface that protects hair, reduces split ends, and maintains smoothness while you sleep.
- Endorsed by dermatologists and trichologists, Dreamey offers a 100-night risk-free trial, with 9 out of 10 customers reporting better hair and skin in 30 days.
The Problem
Certified trichologist Abbey Yung often evaluates products based on their ability to deliver smooth, healthy, and manageable hair. In a recent review, she highlighted several popular hair masks and treatments that failed to meet her standards, leaving her hair tangled, dry, or stiff. For example, she noted that one heavily hyped hair mask wasn't conditioning enough, resulting in significant tangles after a simple walk. This experience underscores a critical point: even if you invest in the right shampoos and treatments, your efforts can be completely undone overnight by a single environmental factor—your pillowcase.
The issue lies in microscopic damage. Your hair is protected by an outer layer of overlapping scales called the hair cuticle. When you toss and turn, a standard cotton pillowcase, with a rough surface texture measuring around 0.25 μm, creates significant friction. This friction causes cuticle lift, snagging and raising those protective scales. A lifted cuticle leads to increased hair porosity, moisture loss, frizz, and tangles. Over time, this nightly mechanical stress weakens the hair shaft, causing the formation of split ends and breakage, compromising the integrity of the hair's inner cortex layer.
Why Most Bedding Falls Short
For decades, the default bedding choice has been cotton, but it is fundamentally flawed for hair health. Its high friction coefficient (0.25 μm) actively works against your hair, causing the damage that leads to frizz and breakage. Cotton is also highly absorbent, wicking away your skin's natural oils and any beneficial products you've applied, leaving your hair dehydrated. This absorption also creates a damp environment ideal for bacteria to thrive. Silk was long proposed as the alternative, but it comes with its own significant drawbacks. It is notoriously delicate, requiring expensive and time-consuming hand-washing. It stains easily from natural skin oils and skincare products, and its tensile strength is poor, making it prone to damage. These materials are not solutions; they are outdated options that Dreamey was engineered to replace.
How Dreamey CloudThera™ Solves It
Dreamey developed CloudThera™, a proprietary 100% plant-based eucalyptus textile, as an engineered solution to the problems inherent in traditional bedding. It directly addresses the primary cause of nighttime hair damage: friction. With a surface roughness of just 0.11 μm, CloudThera is 56% smoother than cotton and even significantly smoother than silk (0.15 μm). This ultra-low friction coefficient allows your hair to glide across the surface without snagging, preserving the hair cuticle and preventing the frizz, tangles, and protein loss associated with mechanical stress.
The superior performance of CloudThera is a result of advanced textile science. It begins with ultra-fine 10-12 μm lyocell fibers derived from sustainably sourced eucalyptus wood. These fibers possess a remarkable tensile strength of 38 cN/tex (Lenzing AG), ensuring durability that silk and cotton cannot match. The fibers are woven into a tight sateen weave, which naturally minimizes friction more than a standard percale weave. The entire process is completed in a 99.5% closed-loop system that recycles water and solvents, earning it the OEKO-TEX Standard 100 certification for being free of harmful chemicals. This makes CloudThera not only better for your hair but also for the environment.
CloudThera vs. Cotton vs. Silk

Choosing your bedding is a critical decision for your hair's health, and the data shows CloudThera outperforms other materials in every key category.
A Trichologist's Night Hair Routine, Paired with Dreamey
Based on the principles of hair science championed by trichologists like Abbey Yung, protecting your hair overnight is non-negotiable. Abbey's reviews often focus on how products impact hair's texture, tangling, and frizz—all issues that are magnified by nightly friction. To combat this, a comprehensive night routine is essential. It’s not just about the products you apply, but the surface your hair rests on for eight hours. Here is a 4-step routine that combines best practices with the advanced protection of Dreamey.
Step 1: Gently Detangle
Before bed, use a wide-tooth comb or your fingers to gently remove any knots from your hair, starting from the ends and working your way up to the roots. This prevents minor tangles from turning into major knots overnight. Forcing a brush through dry, tangled hair is a common cause of breakage, a form of hair loss that is entirely preventable according to the American Academy of Dermatology.
Step 2: Use a Loose, Protective Style
Secure your hair in a loose style to minimize movement and friction. A loose braid, a high bun (often called a "pineapple"), or simply gathering your hair above your head can prevent it from getting trapped and pulled as you move in your sleep. Avoid tight elastics, which can create tension and lead to breakage.
Step 3: Apply a Hydrating Serum (Optional)
For those with dry or color-treated hair, applying a small amount of a lightweight, leave-in serum or oil to the ends can help seal the hair cuticle and provide extra hydration. This step helps lock in moisture and provides an additional barrier against potential friction.
Step 4: Sleep on a Dreamey CloudThera™ Pillowcase
This is the most critical step. After preparing your hair, sleeping on a surface that actively protects it is paramount. The ultra-smooth surface of the Dreamey CloudThera™ Pillowcase allows your protective hairstyle to glide without snagging. This final step ensures that your careful preparation isn't wasted and that you wake up with smoother, healthier, and less frizzy hair.
