"I just had my first consultation with William at his office in Laguna Beach, and it was exactly what I needed. I came in with some mild thinning in my crown and temple regions as a 35 yr old male (mostly thinning in my crown), along with some itchiness/irritation in my crown region, but my goal is to do everything I can to mitigate any future hair loss while my hair is still in good shape. I found William Gaunitz actually through tiktok and Youtube, and I was immediately impressed with his breadth of knowledge and experience. We went into detail about all the hair products/shampoos/topicals I'm currently using, along with any supplements I'm taking, basically getting a full picture of my current protocols and general health. Then we looked at my hair under his microscope device where you can clearly see the health of the scalp and the follicles in all areas of your scalp with extreme detail. Then based on all the information I gave him plus the microscopic analysis, he formulated a plan for me to stop the thinning. We found out I have a lot of demodex parasites growing in my follicles, which is likely causing the irritation and the thinning on top of any genetic factors. So William recommended I take DHT blocker + Follicle Growth serum + Ferratin supplements (all of these are from his Advanced Trichology website), as well as a bunch of other things I can institute into my daily practice to combat my thinning. He also took the time to answer all of my questions that I had written down, questions about minoxidil, medical-grade microneedling, topical finasteride, laser treatments, hair transplants etc. William is an extremely knowledgeable, professional, patient, trustworthy, and thoughtful hair expert who genuinely cares about helping his clients achieve their goals and deal with any hair loss they might be having. He has such a balanced approach between natural remedies and pharmaceutical interventions, and so many years of experience dealing with all types of patients. In an industry with so many questionable 'hair authorities' and products and supplements etc, to me William stands out as an incredibly credentialed and trustworthy expert in his field. I would HIGHLY recommend working with him and getting a solid plan together to help combat your hair loss!"
"I saw Dr Gaunitz for an in clinic consultation and I am impressed by his breadth of knowledge and expertise. He was able to pinpoint the root cause of the problem when another trichologist and my derma couldn’t. He said that my emotional trigger turned into a chemical trigger because I’ve been taking too many supplements for my condition. He outlined a comprehensive care plan that targets all the areas and I’m confident that this time, it’s going to finally work. I’ve already applied the changes he recommended and I can’t wait to see the results."
"If it were not for Evolution and the Advance Trichology products, I would be completely bald. I started losing my hair at age 15. I found Evolution at age 18 and because of them, I still have a full head of hair at age 34. There are a lot of gimmicks out there in the hair loss industry. Finding someone you can trust is key. Evolution takes a holistic approach to hair loss, hitting it from every angle. I could not recommend them more."
