Baby Rash from New Laundry Detergent
Content reviewed against published AAP, NIH, AAP guidelines

Baby skin is sensitive and changes frequently. If you are noticing baby rash from new laundry detergent, here is what you need to know.
The short answer
Rashes from laundry detergent are a form of contact dermatitis and appear as red, itchy patches where clothing touches the skin. Baby skin is thinner and more sensitive than adult skin, making it more prone to irritation from fragrances, dyes, and chemicals in detergents. Switching to a fragrance-free, dye-free detergent and rewashing affected clothing usually resolves the rash within a few days.
Key takeaways
- Rashes from laundry detergent are a form of contact dermatitis and appear as red, itchy patches where clothing touches the skin.

Switching to a fragrance-free, dye-free detergent and rewashing affected clothing usually resolves the rash within a few days.
- Usually normal when: A mild red rash appears in areas where new clothing touches skin and improves after switching detergent.
- Call your doctor if: The rash involves blistering, oozing, or raw open skin.

“Eczema is very common in babies and children. About 1 in 10 children will develop eczema, typically starting in the first few months of life.”
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
0-3 months
Newborn skin is especially delicate and more permeable to irritants. Contact dermatitis from detergent typically appears as red, slightly raised patches where clothing sits against the skin, particularly in creases and areas with friction. It can be difficult to distinguish from other common newborn rashes like eczema or heat rash. Use fragrance-free, dye-free detergent for all baby items, including bedding and burp cloths. An extra rinse cycle can help remove residual detergent.
3-12 months
As babies become more active, clothing rubs against skin more, potentially worsening contact dermatitis. The rash typically appears on the torso, arms, and legs where clothing sits. If you recently changed detergents and notice a new rash pattern, try switching back or to a hypoallergenic alternative. Avoid fabric softeners and dryer sheets, which can also irritate sensitive skin. A mild over-the-counter hydrocortisone cream (0.5% or 1%) may help with itching, but check with your pediatrician first.
12-36 months
Toddlers with sensitive skin may continue to react to certain detergents. If your child has eczema, their skin barrier is already compromised and more susceptible to irritants. Consistent use of gentle, fragrance-free detergent for the whole family is often the easiest approach. If the rash persists despite switching detergents, other causes like eczema, heat rash, or fungal infection should be considered.

Related Conditions
Baby Hives (Urticaria)
Hives are raised, red, itchy welts that can appear suddenly on your baby's skin. They are most often caused by a viral infection or an allergic reaction to food, medication, or an insect bite. While they can look alarming, hives are usually harmless and resolve on their own, though any breathing difficulty needs immediate emergency care.
My Baby Got a Rash After Antibiotics
A rash during or after antibiotics is very common in babies and children, occurring in up to 10% of those taking amoxicillin. Most antibiotic rashes are non-allergic reactions that appear as flat, pink, widespread spots and are not dangerous. However, it is important to distinguish this from a true allergic reaction involving hives, so contact your pediatrician to help determine which type of rash your baby has.
Winter Dry Skin and Cracking in Babies
Baby skin is thinner and more sensitive than adult skin, making it particularly prone to dryness and cracking during winter months when cold outdoor air and dry indoor heating combine to strip moisture. Regular use of a thick, fragrance-free moisturizer (cream or ointment rather than lotion) applied within 3 minutes of bathing is the best prevention and treatment. Limit baths to 5-10 minutes with lukewarm water, use gentle cleansers, and dress your baby in soft fabrics.

My Baby Has an Extra Nipple (Accessory Nipple)
Accessory (supernumerary) nipples are one of the most common minor congenital findings, occurring in about 1 in 18 people. They appear as small, flat, often pigmented bumps along the "milk line" — an embryonic line running from the armpit to the groin on each side. Most people mistake them for moles. Accessory nipples are almost always harmless and require no treatment. In rare cases, they may be associated with kidney abnormalities, so some pediatricians recommend a renal ultrasound if one is found, though this practice varies.
My Baby Was Born with a Raw Spot on Their Scalp (Aplasia Cutis)
Aplasia cutis congenita (ACC) is a condition where a baby is born with a small area of missing skin, most commonly on the scalp. It occurs in about 1 in 10,000 births. The affected area may look like a raw wound, an ulcer, or may have already healed into a thin, shiny scar by the time of birth. Most cases are small, isolated, and heal well with basic wound care — the area eventually forms a hairless scar. Larger defects or those associated with other findings may need more investigation, but isolated small ACC has an excellent prognosis.
New Treatments for Atopic Dermatitis (Eczema) in Children
Treatment for atopic dermatitis in children has advanced significantly in recent years. While moisturizers and topical steroids remain first-line treatments, newer options include non-steroidal topical medications (like crisaborole), biologic therapies (like dupilumab, approved for children 6 months and older), and JAK inhibitors. Most children's eczema is well-managed with basic skin care and mild topical treatments, but these newer options provide hope for moderate-to-severe cases.
