Silk and hair: an ally against breakage
Silk's smooth surface reduces friction compared to rougher fabrics like cotton, which can limit tangling, frizz, and breakage, according to experts ( Sleep Foundation, Benefits of a Silk Pillowcase , 2023 ). Silk also absorbs little moisture, which helps preserve natural oils and moisture.

Why silk is different from cotton
Unlike cotton, whose spun fibers have micro-roughness, mulberry silk is a continuous and smooth fiber. Thus, it lowers the coefficient of friction and is particularly protective for fragile, dry or curly hair .
Nighttime use tips
- Choose a silk pillowcase of at least 19 mommes for a compromise between softness and durability.
- If you wear protective hairstyles, replace the classic elastic with a silk scrunchie to prevent marks and breakage.
- For frizzy, textured or dry hair, a silk nightcap helps retain moisture and reduce frizz.
Silk and Alopecia: What the Experts Say
Alopecia (androgenetic and areata or alopecia areata) is caused by internal genetic, hormonal or immune mechanisms. Dermatologists point out that no silk or cotton pillowcase can stop hair loss related to these causes. In short, silk does not cure alopecia and does not trigger regrowth; it mainly acts to protect existing hair.
Focus on baldness (androgenetic alopecia)
Baldness is one of the most common forms of alopecia. It occurs when hair follicles (hair roots) become sensitive to a testosterone-derived hormone called DHT (dihydrotestosterone). This sensitivity results in a shortened hair cycle: each new hair grows for a shorter time, becomes finer, and eventually stops growing. It is this gradual process that explains the thinning of the scalp over the years. Validated treatments for regrowth and slowing hair loss (minoxidil, finasteride, immunotherapies, transplants) remain the gold standard. However, silk can help preserve appearance by limiting breakage of thinning hair.
In short, silk does not cure alopecia or trigger regrowth; it mainly acts to protect existing hair.
Silk and traction alopecia
Traction alopecia is caused by repeated mechanical stress (tight braids, buns, rigid accessories). Reducing traction is a priority. A silky environment limits additional breakage.
Can silk stimulate regrowth?
No scientific study has demonstrated that silk can directly boost hair growth. Medically validated treatments for regrowth (minoxidil, finasteride, immunotherapies) remain the gold standard. Silk acts more as a preserver: it protects existing or regrowing hair, particularly when it is fine and fragile. A silk nightcap can thus protect fragile new growth after alopecia or chemotherapy.
Silk, comfort even without hair
Even in cases of total hair loss, whether due to advanced alopecia, chemotherapy or another pathology, silk retains all its benefits. Its exceptionally soft texture limits direct friction on the bare scalp, which is often more sensitive and prone to irritation. Sleeping on a silk pillowcase or wearing a silk nightcap provides a feeling of comfort , reduces redness and promotes a more peaceful sleep . More than just an accessory, silk then becomes a protective caress, bringing well-being and comfort where the skin needs it most.
Conclusion
Silk is a valuable ally: it reduces breakage and improves scalp comfort . To date, there is no evidence that it prevents pathological alopecia or directly stimulates regrowth. Therefore, we recommend combining it with appropriate dermatological care for best results.
