Hi, I’m Michelle.

Why I started
Onehappykale.

My own experience with acne changed how I looked at the products I was using. I started Onehappykale because I wanted to create products with ingredients I could feel good about putting on my own skin.

As a Board Certified Integrative Health Practitioner, I’m particular about what goes into my products. Every formula is made with a purpose, using thoughtfully chosen ingredients and a full ingredient list so you know exactly what you’re using.

A few things to know

Let’s make it easy.

Should I start with the spray or the oil?

Choose the spray for a lightweight leave in step. Choose the oil for a prewash treatment. Want both steps? The Mermaid Hair Duo includes one of each.

Do I rinse out Mermaid Hair Spray?

No. Shake, apply to your scalp in sections, and massage. Leave it in and use at least four days per week, following the product directions.

Where can I check the ingredients?

Each product page has its full ingredient list. The spray contains distilled water, aloe vera juice, witch hazel, and lavender, rosemary, and cedarwood essential oils.

When is shipping free?

US orders over $49 qualify for free shipping. Your final shipping cost is shown at checkout.
