The science

Nobody warned you it was coming.
Here is what is actually happening.

Postpartum hair loss follows a predictable biological pattern. Knowing the timeline takes the fear out of the waiting.

The biology

Your hair follicles are not damaged.
They are resetting.

After birth, oestrogen drops sharply. Follicles that stayed in the growth phase during pregnancy begin releasing together. This is telogen effluvium, postpartum hair loss. It is temporary. It is not damage. It follows a predictable pattern, and it has a close.

Birth to month 2

Hormones begin recalibrating

Oestrogen returns toward baseline. Follicles begin transitioning to the resting phase. Most women notice little change at this stage.

Months 3 to 4

Postpartum hair loss peaks

Resting follicles begin releasing together. Most women first notice significant loss here, in the shower, on the pillow, in the brush. It feels sudden. It is the normal biology running its course.

Months 4 to 9

The regrowth window opens

Follicles re-enter the growth phase. New hair begins to emerge. What follicles receive nutritionally during the postpartum hair regrowth window influences the quality and health of what grows back.

Nurishy supports the regrowth window
Months 9 to 12

The regrowth window closes

The follicle cycle completes. New growth is established and density returns toward pre-pregnancy levels. The biology is done. What follows is simply time and length.

The key insight

Postpartum hair loss is not a problem to solve. It is a natural process to support.

The hair will grow back. That is biology. What follicles receive during the postpartum hair regrowth window contributes to the strength, thickness, and health of what grows back. That is the only thing Nurishy is designed to support.

30% of follicles can release together. This is why postpartum hair loss feels so dramatic, and why it is not damage.Galal et al. Journal of Clinical and Aesthetic Dermatology, 2024

``` The formulation logic

Designed alongside your postnatal vitamin.
Not instead of it.

Most women in the postpartum hair regrowth window are already taking a postnatal vitamin. That is correct and should not change. Postnatal vitamins cover general maternal recovery. They were not designed for the postpartum hair regrowth window. Nurishy fills the gap they leave.

01

No overlap risk

Every ingredient is dosed with standard postnatal vitamin coverage in mind. No nutrient is doubled beyond safe parameters.

02

Within every UK and EU safe upper limit

All doses within UK, EU, and EFSA safe upper limits. The formulation was assessed to the safety standard required for breastfeeding women and infants. That is the most stringent benchmark in postnatal nutrition.

03

Every ingredient earns its place

Every ingredient has a specific and evidenced role in follicle health or the regrowth cycle. Nothing earns its place by sounding credible.

04

No botanical risk

Several popular hair supplement ingredients have limited or absent breastfeeding safety data. Nurishy uses only nutrients with established lactation profiles.

The ingredients

Every ingredient
earns its place.

Nothing in here because it sounds good. Everything because the evidence supports its role in the postpartum hair regrowth window, at a dose calibrated for use alongside your postnatal vitamin.

The differentiator Silicon (Bamboo extract) 5mg elemental

Sourced from bamboo extract, one of the most bioavailable plant-based sources of silica. Supports hair shaft structure during the postpartum hair regrowth period, with emerging evidence on tensile strength. Not present in standard postnatal vitamins. Zero overlap risk.

Not in your postnatal vitamin
Hair structure support Biotin 300mcg

UK and EU authorised: contributes to the maintenance of normal hair. Dosed to complement your postnatal vitamin without duplication.

Hair growth cycle Zinc

UK and EU authorised: contributes to the maintenance of normal hair. Calibrated for use alongside standard postnatal vitamins.

Scalp protection Selenium

UK and EU authorised: contributes to the maintenance of normal hair. Calibrated within UK and EU safe upper limits with postnatal coverage accounted for.

Hair pigmentation Copper

UK and EU authorised: contributes to normal hair pigmentation. Not typically present at meaningful levels in postnatal vitamins.

Follicle environment B-complex, D3, C & E Calibrated doses

A complete supporting environment for follicle health. All calibrated within UK, EU, and EFSA safe upper limits for use alongside your postnatal vitamin. Total intake stays within safe parameters throughout.

Deliberate omissions

Two ingredients we chose
not to include. And why.

Most hair supplements contain both. We removed them deliberately. Every omission went through the same evidence review as every inclusion.

Deliberate omission
NURISHY / FORMULATION / 01
Omission 01 Vitamin A 0mg, deliberately

Vitamin A passes through breast milk to a newborn.

Most hair supplements include vitamin A because it contributes to normal cell division. We chose not to. Several competitors include it at levels that, combined with a standard postnatal vitamin, approach the upper safe intake level for breastfeeding women. That felt like an unnecessary risk. We removed it entirely.

Deliberate omission
NURISHY / FORMULATION / 02
Omission 02 Iron 0mg, deliberately

Your postnatal vitamin already covers it.

Iron is present in almost every postnatal vitamin at clinically relevant doses. Adding more in Nurishy creates unnecessary overlap. We calibrated around what you are already taking, not what makes the formula look more complete on paper.

Every omission is as considered as every inclusion.
Safety and transparency

Breastfeeding safe.
At every level of that claim.

Breastfeeding safe is not just a marketing phrase used by Nurishy. It is a formulation standard that governed every ingredient decision from the first draft. Nurishy is safe at every stage of the postpartum hair regrowth window, whether you are currently breastfeeding or not.

Every ingredient assessed. Every dose mapped against UK and EU safe upper limits. Every uncertainty removed from the formula.

All ingredients selected for their established safety profile, assessed to the standard required for breastfeeding women and infants, at doses calibrated for use alongside a postnatal vitamin. Every ingredient is listed in full in the section above.

UK and EU safe upper limits

Every nutrient dosed within established UK and EU safe upper limits, with postnatal vitamin intake accounted for in the total.

Calibrated for use alongside your postnatal vitamin

Total nutrient intake across Nurishy and your postnatal vitamin was modelled together. Every dose was set with combined intake in mind, not in isolation.

No botanicals with uncertain lactation data

Only nutrients with established breastfeeding safety profiles. No herbal ingredient was included unless its lactation safety is established and documented.
