Welcome to Minoval® Hair Regrowth Treatment, Castor Oil. We are dedicated to providing high-quality, all-natural hair care products to help support healthy, beautiful hair. Our story begins with a passion for using natural ingredients to nourish hair from root to tip.
Our Humble Beginnings

Minoval® was founded in 2022 by John Smith, a haircare enthusiast who struggled with hair loss for years. After trying countless conventional treatments with mixed results, John began exploring natural solutions. He discovered that pure, cold-pressed castor oil had been used for centuries to support hair growth and overall scalp health. Inspired by this knowledge, John partnered with a small team of haircare experts to develop an effective regrowth treatment using castor oil as the key ingredient.
After months of researching, testing, and refining their formula, the Minoval® treatment was born. Made with 100% pure Jamaican black castor oil, the treatment leverages the oil’s unique biochemical properties to nourish hair follicles and stimulate growth. John knew he had created something special that could help others on their hair regrowth journey.
Growing Our Product Line
Since those early days, Minoval® has expanded its product offerings while remaining committed to using natural, botanically-derived ingredients free of harsh chemicals. We now proudly offer a full line of haircare products designed to provide complete scalp and strand care.

We round out the line with scalp massagers, hair brushes, micro-fiber towels, and other accessories to enhance the haircare ritual. Minoval® provides a complete solution for supporting robust, healthy hair.
Our Secret: Jamaican Black Castor Oil
The foundation of all Minoval® formulas is hand-pressed Jamaican black castor oil, revered for its ability to nourish follicles and promote growth. Grown and processed in Jamaica according to traditional methods, Jamaican black castor oil differs from other castor oils due to its high concentration of active compounds.
During processing, the castor beans are roasted, husked, and pressed to extract the oil. This artisanal approach makes Jamaican black castor oil exceptionally pure and potent compared to commercial processes that use chemical extraction. The result is an unrefined oil boasting powerful hair-enhancing benefits.
Jamaican black castor oil contains rich levels of:
- Vitamin E: A potent antioxidant that supports scalp health.
- Omega fatty acids: Nourish hair and improve elasticity to reduce breakage.
- Ricinoleic acid: Stimulates blood circulation to improve follicle health.
- Keratin proteins: Adhere to hair strands to reinforce and protect from damage.
This optimal blend of nutrients penetrates deep into follicles and hair shafts to provide intense nourishment that revitalizes hair from the roots up.
We source our Jamaican black castor oil from growers we know and trust. It is always cold-pressed without any chemical additives to preserve its natural properties. Harnessing the oil in its purest form allows us to create products that leverage the full potential of this powerful botanical.
Creating Our Signature Formulas
While Jamaican black castor oil is at the core, our research team meticulously selects each additional ingredient to complement the oil’s properties. We use a proprietary blend of botanical extracts, vitamins, minerals, proteins, and other nutrients proven to optimize hair growth and health.
During formulation, we pay close attention to the latest scientific research on hair loss treatments and natural regrowth methods. Our goal is to translate this research into effective everyday products by choosing clinically-backed key actives and combining them with the nourishing base of Jamaican black castor oil.
We reject overly complex formulas, unnecessary fillers, and synthetic chemicals. Each Minoval® product uses a short list of premium natural ingredients purposefully chosen to target specific hair goals. For example, our Hair Regrowth Drops include:
- Rosemary leaf oil: Shown to improve hair density similar to the prescription drug minoxidil.
- Peppermint oil: Stimulates and refreshes the scalp to optimize growth.
- Biotin: Critical B vitamin that supports production of keratin protein.
- Niacin: Enhances microcirculation in the scalp.
- Vitamin E: Potent antioxidant that protects hair follicles.
This researched blend maximizes regrowth results when combined with our castor oil treatment. We exhaustively test each formula to ensure optimal synergistic effects among the select ingredients.

Our Haircare Philosophy
At Minoval®, we believe caring for your hair should feel good—for you and the planet. We aim to make haircare a ritual to savor focused on wellbeing and natural ingredients.

Meet Our Founder John Smith
Minoval® was founded by John Smith, an avid haircare enthusiast with a personal passion for hair regrowth. After coping with premature hair loss in his 20s, John became determined to find an effective natural solution.
His research uncovered the centuries-long history of using castor oil to support hair health across cultures. Intrigued by this knowledge, John teamed up with expert cosmetic chemists to translate the oil’s benefits into an advanced treatment formula.
Numerous trials and tweaks eventually yielded the first Minoval® Hair Regrowth Treatment—validating castor oil’s potential as a natural alternative to synthetic products. Encouraged by the positive feedback from friends and family, John expanded the brand to create a full line.
Today John remains intimately involved in developing new Minoval® products. He continues to innovate hair-nourishing formulas powered by Jamaican black castor oil and other botanicals.
“After trying every product and prescription out there with minimal results, I became obsessed with finding an effective and holistic solution for hair regrowth,” John says. “The game changer for me was unrefined castor oil, an ancient remedy that academic research also validates. I knew I needed to share this natural secret with others dealing with hair loss and thinning. That passion led me to create Minoval® using high-quality, ethically sourced ingredients you can trust.”
Outside of running Minoval®, John loves surfing, hiking, and spending time with his two dogs. He hopes his products empower people to embrace their hair’s natural beauty.

Giving back to the community and causes we care about is extremely important to us at Minoval®. That’s why we donate a portion of all sales to select nonprofits and charities focused on sustainability, women’s health, and access to education.

I get compliments on how thick and healthy it looks now. Finally seeing results with a product that nourishes my hair makes me feel amazing.” – Sara K.
“My barber first told me I was losing hair in my crown area last year. I decided to be proactive and started using Minoval right away instead of waiting for more hair to fall out. I apply it every night and their hair regrowth drops in the morning. It’s part of my self-care routine now. My girlfriend loves running her hands through my new baby hairs!” –Henry T.
“I love that Minoval products smell like real ingredients — the shampoo and conditioner leave my curls shiny and soft without harsh sulfates. The scrub detoxifies my scalp so well. My hair feels stronger and healthier overall. I am passing along their castor oil treatment to friends dealing with postpartum thinning.” – Olivia P.
“I have struggled with scalp issues for years off and on. Minoval’s scalp scrub is amazing – it has tea tree oil and other ingredients that leave my scalp tingling and fresh. I was nervous to try castor oil because I have fine straight hair that can look oily fast. But it absorbs so well and makes my hair feel stronger. I use the leave-in serum too for heat protectant before styling.” – Monica S.
