Groh® is the mushroom-powered solution to hair loss, for men and women. In addition, Groh® provides a healthy daily routine to fulfill nutritional needs that a simple diet often fails to provide.

Their dietary supplement treatments are formulated to reawaken dormant cells in the hair, scalp, skin, nails, lashes, and eyebrows - as well as support a healthier and more optimized lifestyle.

GROH® products from William Collider Design supply the key micronutrients necessary to help stimulate new hair growth, improve overall scalp health and create a better sense of well-being. So if you suffer from thinning or receding hair lines, GROH® is the answer. Their exclusive natural formula works to awaken dormant hair follicles, promoting fuller, thicker hair, lashes and brows. With proper styling, you'll be looking better in no time.

  • Groh® is the first hair health system to address both internal and external hair growth processes
  • Effective for women & men of all ages
  • FDA approved ingredients
  • Groh® hair care products contain no parabens, sulphates, GMOs, petrochemicals, petroleum or artificial colors. 
  • Groh® does not utilize animal testing 

The Secret Is Ergo and Vitamin D

Groh®'s effectiveness for new hair growth stems from a natural combination of the amino acid Ergothioneine and Vitamin D2, a combination that cannot be manufactured by humans and can be obtained only through diet. This natural combination, found within specialty mushroom plants, and enriched through a patented process, is incorporated into our natural supplements and external skin products. This signature formula is one of the most potent methods known to date for stimulating healthier, thicker and fuller hair, lashes and brows.

William Collier Design is proud to offer the HairMax LaserBand 82 as another great system to promote hair growth. We chose this device because of it's ease of use and as the fastest treatment available...only 90 seconds, 3 times a week. 

This unique band design incorporates patented hair parting teeth to part your hair during treatment to maximize laser light delivery to your follicles. The hair parting teeth, the laser light intensity and laser light density work in unison to provide a highly effective treatment. Without hair parting teeth, the hair can block a majority of the laser light energy from reaching the follicles.

The LaserBand 82 is lightweight, comfortable, portable and convenient for home use or while traveling. No heavy battery packs to carry around.

RevitaLash Cosmetics

RevitaLash Cosmetics, the leading Physician led, award-winning line of lash, brow and hair focused cosmetics specifically designed to elevate, restore, and enhance the health and natural beauty of your most treasured beauty assets.

A proud year-round supporter of breast cancer awareness, research and education, we hope you’ll join us and RevitaLash in efforts to eradicate women’s cancers, while inspiring beauty and life quality, a goal which is at the heart of RevitaLash Cosmetics. Established in 2006, our story began with just one product – their original lash conditioning serum – inspired by the immense love between their founder and his beloved wife Gayle, as a solution to help her feel beautiful during her courageous fight against breast cancer. From that single, original product comes an entire collection of beauty-enhancing, solution-oriented cosmetics that revitalize the natural beauty and inner spirit of all women, while giving back to the cause that started it all.

VOLUME ENHANCING FOAM addresses the needs of both men and women concerned with fine, thinning or lackluster hair; which features the power of RevitaLash science for the hair. A unique recipe of ingredients called BioPeptin Complex is their proprietary blend of lipids, peptides, Biotin and Panthenol. Biotin, also known as Vitamin B7, contributes to the production of healthy hair and nails by providing essential ingredients in the process of hair enhancement. Panthenol, also known as Vitamin B5, helps to smooth and strengthen hair. This rich combination of B vitamins, along with peptides and antioxidants, work to fortify hair and reduce brittleness and breakage, resulting in stronger, healthier hair. Volume Enhancing Foam improves hair elasticity and aids in conditioning of the scalp too! 

This product is a Physician developed formula that draws on over a decade of formulation expertise. We carry many products of the RevitaLash line including:

THICKENING SHAMPOO & CONDITIONER - to be used in conjunction with the Volume Enhancing Foam. A unique thickening and scalp therapy shampoo features specialized ingredients to optimize scalp health by cleansing and fortifying hair while protecting from environmental stressors.
