LILYSILK Review: Modest Real Benefit, Big Claims
LILYSILK sells mulberry silk bedding, sleepwear and clothing, generally from about $119 upward. Silk pillowcases are the product most people encounter first and the one with the most claims attached. The honest position is that there is a modest real mechanical benefit and the marketing extends well past it — which matters more than usual for readers here, because hair shedding a few months into weight loss is common and people go looking for solutions.

Verdict: Genuine quality with a benefit that is real and smaller than advertised. Silk has a smoother surface than cotton and produces less friction against hair and skin, which plausibly reduces mechanical breakage and creasing — a modest mechanical effect rather than a treatment. Momme weight is the specification that actually distinguishes silk products and is frequently buried; higher momme means denser, more durable fabric. What silk does not do is affect hair growth, and for anyone shedding during weight loss the causes are nutritional and the answer is elsewhere.
What LILYSILK Costs
Mulberry silk pricing with momme weight as the specification that matters.
| Plan | What you get | Listed | Real cost |
|---|---|---|---|
| Pillowcases | Mulberry silk | From around $50 upward | Momme weight is the spec |
| Bedding sets | Sheets and duvet covers | $119 to $199 and up | Substantial investment |
| Sleepwear and clothing | Silk garments | Varies | Care requirements differ |
| Momme weight | Fabric density specification | Check it | 19–25 is the usual quality range |
Silk does not affect hair growth or shedding
Reduced friction plausibly reduces mechanical breakage of existing hair, which is a modest real effect. It has nothing to do with hair growth or with shedding. Shedding that begins two to four months into rapid weight loss is typically telogen effluvium — triggered by physiological stress, sharply reduced calories or inadequate protein, and self-limiting within six to nine months. What addresses it is adequate protein, and having iron and ferritin, thyroid function and vitamin D checked by a doctor. A pillowcase does not enter into it, and buying one instead of addressing the cause delays the thing that helps.
Momme weight is the specification separating quality silk from thin silk sold at similar prices. Look for it and be sceptical when it is not stated.
What momme weight tells you
Momme is the traditional measure of silk fabric weight, and it is the specification that distinguishes products more than anything else. Higher momme means denser fabric — more durable, more opaque, and considerably more expensive to produce.
Roughly 19 to 25 momme is the usual quality range for bedding. Below that, fabric is thin and wears quickly; above it, cost rises steeply for diminishing returns.
A product not stating momme weight is omitting the number that matters, which is worth noticing. Two silk pillowcases at similar prices can differ substantially in this specification.
Mulberry silk refers to the silkworm diet and produces longer, more uniform fibres than wild silk varieties. It is a genuine quality indicator alongside momme rather than instead of it.
The actual benefits, honestly scoped
Reduced friction is the mechanism, and it is real. Silk has a smoother surface than cotton, so hair moves across it with less mechanical resistance — plausibly less breakage and less of the tangling that causes damage when brushing out in the morning.
The same applies to skin creasing. Sleep creases from a cotton pillowcase are temporary and silk produces fewer of them, which is a cosmetic rather than a dermatological effect.
Silk is also less absorbent than cotton, so it draws less moisture from hair and skin. For anyone dealing with dryness — common during weight loss as fluid intake falls alongside food — that is a small point in its favour.
What silk does not do: affect hair growth rate, prevent shedding, treat any skin condition, or substitute for moisturiser and sunscreen. The claims in this category routinely extend past the mechanism.
If your hair is shedding
Shedding starting two to four months into rapid weight loss is characteristically telogen effluvium. Rapid loss, sharply reduced calories and inadequate protein are all recognised triggers, and the delay is because of how the hair cycle works.
It is diffuse rather than patchy, and it is self-limiting — usually resolving within six to nine months once the trigger settles.
What helps: adequate protein, which is the same advice that protects your muscle, and having a doctor check iron and ferritin, thyroid function and vitamin D. Low iron stores are associated with shedding even when haemoglobin looks normal.
Be gentle with what you have — lower heat styling, less frequent, careful brushing when wet. A silk pillowcase fits in that category of reducing mechanical stress, which is a supporting measure rather than a solution.
If loss is patchy rather than diffuse, or does not improve, see a doctor. That is a different picture.
Pros and Cons
Strengths
- Reduced friction plausibly reduces mechanical hair breakage
- Less absorbent than cotton, which helps with dryness
- Momme weight gives a verifiable quality specification
- Durable when the momme weight is adequate
Drawbacks
- No effect on hair growth or shedding despite category marketing
- Premium pricing across the range
- Requires more careful laundering than cotton
- Momme weight frequently unstated by lower-quality sellers
Who Should Pick It — and Who Shouldn't
Good fit
Someone who wants reduced friction for hair and skin, checks momme weight before buying, and understands it is a mechanical benefit rather than a treatment.
Look elsewhere
Anyone shedding hair during weight loss who buys this instead of checking protein, iron and thyroid — that is the thing that actually helps.
Frequently Asked Questions
Do silk pillowcases help with hair?
Modestly and mechanically. Silk produces less friction than cotton, which plausibly reduces breakage and tangling. It has no effect on hair growth or shedding, and the marketing in this category routinely extends past the mechanism.
Why is my hair shedding on a GLP-1?
Most likely telogen effluvium — rapid weight loss, sharply reduced calories and inadequate protein are recognised triggers, and shedding appears two to four months later. It is diffuse rather than patchy and usually resolves within six to nine months.
What actually helps hair shedding during weight loss?
Adequate protein, and having a doctor check iron and ferritin, thyroid function and vitamin D — low iron stores are associated with shedding even when haemoglobin looks normal. Be gentle with heat styling and brushing meanwhile. If loss is patchy, see a doctor.
What is momme weight?
The traditional measure of silk fabric density, and the specification that distinguishes quality more than anything else. Roughly 19 to 25 momme is the usual quality range for bedding. A product not stating it is omitting the number that matters.
Considering LILYSILK?
Check momme weight before buying silk. And if your hair is shedding, check protein, iron and thyroid — that is where the answer is.
