As I Am Rosemary Shampoo review: refreshing and well built, but not a hair-growth treatment
A thoughtful cleansing formula with a cooling rosemary-and-mint character. The ingredients make sense for wash day, but the evidence does not support treating this rinse-off shampoo as a hair-growth solution.

Consider it if you want a scalp-focused shampoo that combines a mild-looking cleanser system with conditioning ingredients and a noticeable cooling sensation. Skip it if fragrance, essential oils or menthol tend to bother your scalp. Most importantly, buy it as shampoo, not as a treatment for hair loss.
- Best for
- Curls, coils or other hair types that need a proper cleanse without choosing an obviously aggressive clarifying formula.
- Skip it if
- Your scalp reacts to peppermint, menthol or fragranced essential oils, or your main goal is treating unexplained hair loss.

The short version
- The formula pairs several relatively mild surfactants with betaine, glycerin and conditioning polymers.
- Rosemary, peppermint and menthol create the product's scalp-focused identity and its likely cooling sensation.
- Evidence for topical rosemary oil cannot be transferred directly to a rinse-off shampoo.
- DealOtter has not performed a hands-on test, so the verdict is based on the published formula, directions and external observations.
The short answer
As I Am Rosemary Shampoo looks more convincing as a cleanser than as a growth product. Its ingredient list has a coherent wash-day structure: cleansing agents near the top, humectants and conditioning polymers to soften the result, and an aromatic rosemary-and-mint blend that gives the line its identity.
That makes it a reasonable candidate for someone who wants a refreshing scalp cleanse and dislikes the stripped feeling that can follow a hard clarifying shampoo. It does not make it a proven answer to thinning hair.
What the formula tells us
The official ingredient list starts with water, disodium cocoamphodipropionate, betaine and disodium laureth sulfosuccinate. Those are followed by cocamide MIPA and additional cleansing agents further down. On paper, this is a mixed surfactant system designed to lather and clean without relying on one especially aggressive detergent.
Betaine and glycerin help with moisture, while polyquaternium-7 and polyquaternium-10 are conditioning polymers that can improve slip and reduce the rough feel after rinsing. Ceramide NP and copper tripeptide-1 are interesting additions, although their position in a rinse-off formula makes it sensible to keep expectations modest.
The manufacturer instructs users to apply the shampoo section by section, massage it into the scalp, carry the lather through the lengths, leave it briefly and rinse. The pointed nozzle suits that scalp-first approach.
The rosemary claim needs context
The best-known human study compared rosemary oil with 2% minoxidil over six months in people with androgenetic alopecia. That small randomized comparative trial studied a topical oil regimen, not this product and not a shampoo that is rinsed away after a few minutes.
The distinction matters. Contact time, concentration and delivery system all change what an ingredient can do. The presence of rosemary oil, biotin, melatonin or copper peptide does not demonstrate that the finished shampoo regrows hair. DealOtter would not use it in place of a diagnosis or an evidence-based treatment.
If shedding is sudden, patchy, painful or persistent, the American Academy of Dermatology recommends seeing a dermatologist to identify the cause rather than relying on cosmetic products.
What shoppers consistently notice
Customer feedback on the Walmart review page repeatedly mentions lather, a clean scalp, a cooling or tingling sensation and a noticeable rosemary or mint smell. Those are anecdotal observations, not controlled testing. Some reviews are also marked as incentivized, which is another reason not to treat the rating as scientific evidence.
Still, the pattern matches the formula. Peppermint oil and menthol can explain the cooling sensation, and the surfactant blend is consistent with a shampoo designed to foam well. The scent is likely to be part of the experience rather than something that disappears unnoticed.
The main reason to skip it
Rosemary oil, peppermint oil, menthol, limonene and linalool are the ingredients most likely to give a fragrance-sensitive shopper pause. A safety assessment from the Cosmetic Ingredient Review Expert Panel concluded that rosemary-derived cosmetic ingredients are safe as used when products are formulated to be non-sensitizing. That does not mean every individual scalp will tolerate every aromatic formula.
If you have eczema, a damaged scalp barrier or a history of reactions to fragranced products, a simpler fragrance-free shampoo is the more cautious first choice. Stop using the product if it causes persistent burning, redness or itching.
Our verdict
There is a good shampoo idea here. The cleansing base, humectants and conditioning polymers are more important to that conclusion than the fashionable ingredients on the front label. For people who enjoy a brisk, cooling wash and want a formula aimed at curls and coils, it deserves consideration.
The trade-off is equally clear. The aromatic ingredients may be too much for a reactive scalp, and the hair-growth framing runs ahead of what can be concluded from a rinse-off cosmetic. Judge it by how well it cleans and how your hair feels afterward.
FAQ
Does As I Am Rosemary Shampoo regrow hair?
There is no product-specific evidence showing that this rinse-off shampoo regrows hair. Research on topical rosemary oil used a different format and much longer contact time.
Is it sulfate-free?
The published ingredient list does not contain sodium lauryl sulfate or sodium laureth sulfate. It does contain disodium laureth sulfosuccinate, which is a different cleansing ingredient despite the similar name.
Is it suitable for a sensitive scalp?
Not the most cautious first choice. Rosemary oil, peppermint oil, menthol, limonene and linalool can be uncomfortable for some fragrance-sensitive or reactive scalps.
Can every hair type use it?
The brand markets it for all hair types, but the more useful question is whether you enjoy a cooling aromatic shampoo and whether its level of cleansing fits your routine.
