Does rosemary shampoo regrow hair?

We don't claim it does. Some clinical literature suggests rosemary may help with scalp coverage over months of consistent use, but the studies are small and the EU does not permit cosmetic products to make medicinal claims about hair growth. If you are experiencing significant or sudden hair loss, see a dermatologist or trichologist - this is a medical question, not a soap question.

How often should I use rosemary shampoo?

Two to three times a week is a sensible starting point. Daily use is fine for most scalps but unnecessary - the rosemary doesn't accumulate, and over-washing can dry the scalp and irritate it, which is the opposite of what you want.

When would I see a change in hair body or thickness?

Hair grows roughly a centimetre a month. Any change in the visible body of the hair from a scalp-applied product takes at least three months to read clearly, often six. Don't expect cosmetic results sooner than that. If you want to assess honestly, take a photo on day one and again at month three under the same light.

Is rosemary safe during pregnancy?

Cosmetic-concentration rosemary in a shampoo formulation is generally regarded as safe during pregnancy. Concentrated rosemary essential oil applied directly is not recommended at high doses. If you are pregnant and unsure, ask your midwife before introducing any new essential-oil product.

Can I use this on colour-treated hair?

Yes. The shampoos in this range are sulfate-free, which is gentler on dyed hair than most mainstream shampoos. The bigger threats to colour are hot water and over-washing - both of which strip dye faster than any single ingredient.

When should I see a doctor?

Sudden hair loss, patchy bald spots, scalp pain, persistent itching, or significant shedding outside the normal seasonal pattern all warrant a dermatologist or GP visit. Cosmetic products cannot diagnose or treat the underlying causes - thyroid imbalance, iron deficiency, alopecia areata, post-pregnancy telogen effluvium and others - and you don't want to spend three months on shampoo when a blood test would have answered the question in three days.

Concern · thinning or fine hair

Hair-care for thinning or fine hair

Plant-based hair-care our customers have reached for as seasons or stress have changed the body of their hair. Not medicine. We do not treat hair loss; we make rosemary, laurel and green-tea formulations that have been part of Levantine hair tradition for centuries.

What's traditionally been used

Mediterranean and Levantine hair-care has leaned on three plants for as long as written records exist: rosemary, laurel berry oil, and olive oil. They were used long before any modern cosmetic-industry claim was attached to them, mostly as part of weekly bathing rituals rather than targeted treatments. Modern published research on rosemary specifically has been encouraging - small clinical comparisons of dilute rosemary oil with topical minoxidil have shown comparable scalp-coverage results over months of consistent use - but the literature is not large enough for us to make medical claims, and we don't. The products on this page are formulated around the traditional ingredients without making promises about results.

Why we ask you to patch-test rosemary

Rosemary essential oil is a potent active. Some people experience a brief warm tingling on the scalp that fades within minutes; others find the same sensation uncomfortable. A small minority report itching or redness, especially on already-irritated scalps. Always patch-test on a small section of scalp behind the ear before regular use - apply a drop, leave for a few hours, wash off, and only proceed if there's no reaction. People with eczema, psoriasis or seborrheic dermatitis on the scalp should consult a dermatologist before starting any rosemary product, including ours.

Ingredients to favour, ingredients to avoid

Favour

Rosmarinus Officinalis (Rosemary) Leaf Oil (cosmetic concentration)
Laurus Nobilis (Laurel) Fruit Oil
Camellia Sinensis (Green Tea) Leaf Extract
Olea Europaea (Olive) Fruit Oil
Allantoin
Niacinamide (below 4%)

Avoid

SLS - Sodium Lauryl Sulfate
SLES - Sodium Laureth Sulfate
Heavy silicones (Dimethicone, Cyclopentasiloxane in build-up formulations)
Frequent heat-styling above 180 deg C
Alcohol-based dry shampoos used daily
Tight ponytails and traction styles for prolonged periods

Patch-test before you use it on the face.

Apply a coin-sized amount on the inside of the elbow. Leave for 24 hours. If there is no redness, itching or burning, the product is unlikely to provoke a contact reaction. Repeat for every new product, one at a time, with a week between introductions so reactions can be isolated.
