Somewhere around the three-month mark, many new mums notice their skin feels different — tighter, drier, more easily irritated. Then the hair starts shedding in alarming handfuls. And through all of this, the ordinary routine of shaving your legs or underarms suddenly needs a rethink.
Good news first: shaving is entirely safe while breastfeeding. No chemical compound from a razor or a gentle shave gel enters your milk supply. The adjustments you need are about comfort, not safety — because the skin you're shaving right now is not quite the same skin you had before.
Here is what is actually happening, and how to work with it.
Why Your Skin Feels More Sensitive Right Now
Postpartum hormonal shifts affect your skin in ways that are well documented in dermatology. After birth, oestrogen and progesterone drop sharply. If you are breastfeeding, oestrogen stays suppressed for longer — sometimes for the entire duration of lactation — while prolactin rises to support milk production.
This matters for shaving because oestrogen plays a direct role in skin hydration. Lower levels reduce the skin's production of hyaluronic acid and collagen, which compromises the skin barrier and increases transepidermal water loss. In plain terms: your skin holds onto moisture less efficiently, which makes it drier, thinner, and quicker to react to friction.
Prolactin adds another layer. Dermatologists note that prolactin affects sebaceous glands, hair follicles, and skin immune function — meaning your skin's inflammatory response can be more easily triggered than it was pre-baby.
None of this is permanent. For most women, skin gradually normalises once breastfeeding ends and hormone levels restabilise. In the meantime, small changes to your shaving routine make a meaningful difference.
What Happens to Body Hair While Breastfeeding
The striking hair loss many women experience postpartum — formally called telogen effluvium — is caused by falling oestrogen levels. During pregnancy, high oestrogen keeps more hairs locked in the growth phase for longer than usual. After birth, oestrogen drops and those hairs enter the shedding phase together.
The American Academy of Dermatology notes that shedding typically peaks around four months postpartum and resolves by the baby's first birthday for most women. If you are breastfeeding, the drop in oestrogen is more prolonged, so you may find the shedding appears a little later — closer to five or six months — and takes slightly longer to settle.
This primarily affects scalp hair, but some women notice their body hair becoming finer, sparser, or patchier in places too. Others find no change at all. Both are normal variations.
How to Shave Comfortably During This Season
Prioritise hydration before and after
Because your skin barrier is more compromised, preparing the skin matters more than usual. Shave after a warm shower when the hair is softened and the skin is supple. If you have time, let your skin sit under warm water for a couple of minutes before bringing the razor in — it reduces drag significantly.
Straight after shaving, apply an unscented moisturiser while the skin is still slightly damp. This helps seal water into the skin before it evaporates.
Choose a sharp blade and use it gently
A dull blade is the enemy of sensitive skin at any time, and especially during the postpartum period. Dull edges require pressure and multiple passes, both of which increase friction and the risk of irritation, nicks, and ingrown hairs.
A quality safety razor with a fresh blade — like the Freya starter kit — gives you a single, sharp edge that cuts cleanly with minimal pressure. You follow the razor's weight rather than forcing it. That controlled, low-drag stroke is much kinder to skin that is already working harder to maintain its barrier.
Shave with the direction of hair growth on sensitive areas (knees, underarms, bikini line), especially if you are prone to redness or bumps right now. You can do a careful second pass against the grain on legs if you want a closer result, but only if the skin feels comfortable after the first pass.
Keep your products simple and fragrance-free
Fragrances and alcohol are among the most common causes of contact irritation on sensitive skin. While breastfeeding, it is worth temporarily switching to an unscented shave gel or cream — a plain, hydrating formula without essential oils or strong botanical extracts. If something stings or leaves a red flush, that is your skin telling you the formula is too much right now.
Give underarms extra care
Underarm skin is thin and sits in a warm, enclosed area — conditions that make irritation linger longer. If you are experiencing any changes in body odour postpartum (a common side effect of hormonal shifts and night sweats), you may be switching deodorants more frequently, which adds to skin load. Shave gently, rinse thoroughly, and let the skin air for a minute before applying anything else.
Areas That Need Extra Thought
The bikini line
Postpartum skin in this area can be more reactive than usual, particularly if you had a vaginal birth or any perineal healing. There is no medical reason to avoid shaving once healing is complete and you are comfortable — but if the skin feels fragile, there is no urgency either. Waiting until the skin feels settled is entirely reasonable.

Stretch marks and skin that has changed texture
Stretch marks are areas of disrupted skin architecture and can be more sensitive to friction. A very light touch, a well-lubricated blade, and no pressure at all over these areas keeps things comfortable.
When to Pause and Check In
Shaving is low-risk, but a few signals are worth noting:
- Persistent redness or bumps that do not settle within 24 hours may indicate folliculitis or a reaction to your shave product — try switching to something simpler.
- Unusual dryness or cracking suggests the skin barrier needs more support before you shave again; moisturise consistently for a few days first.
- Any area that is healing (scars, incisions, irritated skin) should be left alone until fully closed and comfortable.
If in doubt, your GP or midwife is always the right first call for anything that looks inflamed or does not resolve.
The Short Version
Your postpartum skin is doing extra work under a different hormonal environment. Shaving is safe — you just want to reduce friction, keep products simple, and give the skin the moisture it is less able to hold onto itself right now. A sharp blade, minimal passes, and an unscented routine will carry you through this season comfortably.
Frequently Asked Questions
Is shaving safe while breastfeeding?
Yes, shaving is completely safe while breastfeeding. Razors and standard shave gels do not introduce any substances into breast milk. The main consideration is comfort — postpartum hormonal shifts can make skin drier and more reactive, so technique and product choice matter more than usual.
Why does my skin feel so dry and sensitive since having a baby?
Lower oestrogen levels during breastfeeding reduce the skin's ability to produce hyaluronic acid and retain moisture, leading to dryness, tightness, and increased reactivity. Elevated prolactin also affects skin immune function. These changes are temporary and typically resolve as hormones restabilise after breastfeeding ends.
Why am I losing so much hair postpartum — and will body hair change too?
Postpartum hair shedding (telogen effluvium) is caused by falling oestrogen after birth, which triggers hairs that were held in the growth phase during pregnancy to shed simultaneously. The American Academy of Dermatology notes it typically peaks around four months postpartum and resolves by the baby's first birthday. Body hair changes are less consistent — some women notice finer or sparser hair, others notice no change.
What type of razor is best for sensitive postpartum skin?
A safety razor with a fresh, sharp blade is a good choice for postpartum skin. A single sharp edge cuts cleanly with very little pressure, reducing friction and the risk of irritation. Avoid pressing hard or making multiple passes over the same area, and always shave on well-hydrated, lathered skin.
Are there any areas I should avoid shaving postpartum?
Most areas are fine once you feel comfortable and any birth-related healing is complete. The bikini line and perineal area should be left until you are fully healed and the skin feels settled — there is no medical urgency to rush. For any area with stretch marks or changed skin texture, use a very light touch and ensure the blade is sharp to minimise drag.
