Bloom, our brand-new rosemary shampoo bar for hair growth, is formulated especially to promote stronger, fuller-looking hair with a little help from Mother Nature’s greatest haircare secrets: rosemary, peppermint, and lavender.
Let’s break down the 5 rosemary shampoo bar benefits for hair growth and why Bloom might just be the best shampoo for hair growth you’ve been waiting for.
What’s All The Buzz About Rosemary For Hair Growth?
Rosemary isn’t just for roasted potatoes and your favorite essential oil diffuser blend. It’s also one of the most talked-about natural ingredients for healthier-looking hair (and for good reason!)
Long before TikTok hacks and clinical trials, rosemary was a well-kept beauty secret passed down through generations. Used in Ancient Greece, Rome, and Egypt, rosemary was believed to boost memory, improve circulation, and, you guessed it, promote hair growth.
Fast forward a few thousand years and science is catching up with tradition. The herb’s essential oil is now being studied and praised for its ability to support healthier hair, from root to tip.
That’s exactly why we made it the hero of Bloom, our new rosemary shampoo bar for hair growth. This zero-waste bar is designed to help your hair thrive, naturally.
5 Rosemary Hair Benefits

1. Studies Suggest It Supports Hair Regrowth
A 2013 study found that rosemary leaf extract encouraged hair regrowth in mice with testosterone-induced hair loss, likely by inhibiting DHT, a hormone linked to hair thinning. While the study wasn’t conducted on humans, it laid the groundwork for rosemary’s place in hair loss research.
2. It Can Match Conventional Hair Loss Treatments, Without The Side Effects
A 2015 clinical trial compared rosemary essential oil to Minoxidil 2%, a common pharmaceutical treatment for alopecia. After six months, both groups saw significant hair growth, but the rosemary group reported less scalp itching.
3. It Boosts Scalp Circulation
Good blood flow = a healthy scalp! Rosemary oil helps stimulate circulation to the scalp, which may provide the hair follicles with more nutrients and oxygen, encouraging stronger growth from the root.
4. It Supports Scalp Health, Reducing Itchiness
Rosemary has antimicrobial and anti-inflammatory properties, which can help reduce itchiness, irritation, and flakiness on the scalp. A healthy scalp creates a better environment for healthy hair.
5. It Protects Hair Follicles
By reducing oxidative stress and inflammation, rosemary may help protect hair follicles from damage. This keeps them active and ready to grow your best hair yet.
No wonder rosemary for hair growth is getting the spotlight!
Bloom: The Best Shampoo Bar For Hair Growth!
We took all the goodness of rosemary and infused it into Bloom, our newest shampoo bar formulated to support stronger, fuller-looking hair. But we didn’t stop there. We added:
Peppermint Oil
Peppermint doesn’t just smell amazing, it boosts circulation to the scalp, delivering nutrients to your hair follicles and encouraging healthy growth. That refreshing tingle? It’s working!
Lavender Oil
Lavender soothes the scalp and reduces inflammation. It also helps calm the nervous system, which is great news because stress is a common cause of hair loss. Plus, its antifungal properties support a cleaner, healthier scalp.
Castor Oil
Rich in ricinoleic acid and omega-6 fatty acids, castor oil deeply nourishes the scalp, helps balance natural oils, and strengthens hair at the root. It's a long-trusted remedy for promoting thicker, healthier hair.

How to Maximize the Benefits of Bloom Rosemary Shampoo Bar

Want to make the most of your rosemary shampoo bar for hair growth? Here are a few pro tips to boost your results and give your hair every advantage:
1. Massage It In
Take a minute or two to really work the lather into your scalp. This helps stimulate blood flow (hi again, circulation!) and allows the essential oils to absorb more effectively.

Hair growth takes time. Use your rosemary shampoo bar consistently (at least 2-3 times a week) for several weeks to start seeing noticeable results. Trust the process!
3. Pair With a Conditioner Bar
For maximum softness and strength, follow up with the matching nourishing conditioner bar. It'll help seal in moisture and keep your strands smooth.

Extend the life of your bar by keeping it dry between uses. Here’s how to store shampoo bars like a pro.
