Your hair is so important to framing your face and helping project the image that you desire to the world. We understand that time and genetics sometimes conspire to cause hair loss and alter this image in a way that you wouldn’t choose.

He understands that hair restoration is a private procedure, and he and his entire staff is committed to providing you with an outstanding experience worth telling your friends and family about – but you don’t have to! Downtime is minimal, and results are remarkably predictable, yet appear gradually over about one year, so no one needs to know you had anything done.

He is currently an Associate Clinical Professor at the LSU Health Sciences Center.
Hair transplantation can be quite simple. We know that the hair on the back and sides the scalp tends to be permanent in most individuals even in advanced stages of hair loss. This is due to the fact that these follicles are not affected by the hormone dihydrotestosterone (DHT). This resistance to DHT is a genetic characteristic and remains with the follicle even if transplanted from one part of the scalp (or body) to another. Therefore, permanent hair transplanted to a bald area will continue to grow at its new location.
It is important to understand that during the hair transplant we are not creating new hair. We are simply redistributing hairs from a donor site to cover areas of thining hair. The result is a natural evenly placed hairline and the look of more hair.
A careful assessment by the surgeon is paramount to the success of this procedure. There are factors that determine the number of grafts needed to achieve optimal results. Typical procedures result in 2000-2500 transplanted grafts.
Up to 95% of men with thinning hair can blame it on hormones and genetics It usually follows a pattern of receding hairline and hair thinning on the crown, and is caused by hormones and genetic predisposition. Each strand of hair you have sits in a follicle. Generally, baldness occurs when the hair follicle shrinks over time, resulting in shorter and finer hair. Eventually, the follicle does not grow new hair. The follicles remain alive, which suggests that it is still possible to grow new hair. This is when topical agents and low level light therapy can help revive these weakened follicles.
The reason for female pattern baldness is not well understood, but may be related to:
• Aging
• Changes in the levels of androgens (male hormones). For example, after reaching menopause, many women find that the hair on their head is thinner, while the hair on their face is coarser.
• Family history of male or female pattern baldness.

· Hair Restoration Surgery
· PRP Growth Factors Injections
· Topical Therapies

The location of the donor site is planned by the surgeon. A numbing agent is used to make the donor dissection painless. Many patients opt to have minor sedation to ensure a relaxed experience. Once the follicular graft is obtained, the donor site is closed with tiny clips. These are removed in 7 days. The donor graft is passed under microscopes to divide into smaller follicular units. This ensures graft vitality. Once the follicular units are obtained the next process begins, slivering. Slivering is when the experienced hair technician trims the graft down to 1, 2, 3 or 4 follicles per graft. This is determined by the surgeon. Single hair grafts are usually placed along the hair line and then as the hairs increase in density the 2, 3 and 4 follicle grafts can be used. This gives the most fullness. Slivering and placing is done simultaneously to ensure a seamless transplant procedure. Once all the grafts are placed, PRP can be injected into the scalp to add the benefit of natural growth factors to transplanted grafts. Once complete the patient is sent home with specific instructions which entail graft hydration with a simple water spritzer. It is recommended to obstain from exercise or other exertional activities for 10-14 days.
The first hair cut can take place approximately 4 weeks after surgery. Many patients will notice the grafts are gone. This is expected. The follicles are there in the scalp but the hairs will fall out. Over the next 6-8 weeks the new hairs will grow from these transplanted follicles. Final result can take 6 - 12 months. Some patients opt to have an additional transplant if more fullness is desired.
I had a wonderful experience with Dr. Perenack and the staff at Williamson Cosmetics before, during, and after my procedure. During my consultation appointment, I was able to share my concerns and the results I was looking for. Dr. Perenack offered me different options, some I had not thought of. After my procedure, my recovery time was minimal. I am extremely happy with my final results, I finally look the way I feel inside.
Thank you so much!

I had an eyebrow lift procedure done by Dr.Perenack in 2012, so I knew that he was the Doctor to see when I was considering additional plastic surgery. I’m now 2 weeks out from a neck lift and I am extremely satisfied with the results. The entire experience at Williamson Cosmetic Center has been so positive. All of the staff are very professional and made me feel very comfortable. They answered all of my questions and were easy to contact. I would definitely recommend this Center if you are considering any type of plastic surgery. They are the best!!!!

I have seen Dr. Perenack on multiple occasions. Each experience was nothing short of amazing. His honesty and Eye for perfecting the tiny insecurities we have is astounding. I recently had a surgery with Dr. Perenack in which I opted to only use local anesthesia, at first I was nervous, but he did a wonderful job at calming me down and getting me through it. It was PAINLESS! He talked to me and joked the entire procedure and honestly, I forgot I was even nervous in the first place. My healing was fast and easy and I absolutely love my results! He knew exactly what I was looking for, hitting the nail right on the head! To top off my great experience, his staff could not have been any better. They told me exactly what to expect and there were no hidden surprises. They graciously answered all of my questions and concerns both inside the office and out. The price was reasonable and I was back up and at it after only two short days. I would highly recommend Dr. Perenack!
-Angelle
Dr Perenack was wonderful to work with ! He made me feel extremely comfortable and showed me his own prior work that would be similar to my case and explained everything prior to procedure. My expectations were exceeded and highly recommend ! His PA, Kristi Robert, performs all my injectables and she is fantastic ! She also finds time to fit me in her schedule and so personable.
Thank you Dr Perenack and Kristi

I had a rhinoplasty and lower eyelid surgery done by Dr Perenack and I couldn't be happier. Dr Perenack is the best of the best and I was confident to let him work on my face. My nose always bothered me and I hated the way it looked in photos, but now I don't have to worry about that at all and love my profile! Having my lower eyelids done makes me look younger and refreshed. I would 100% refer Dr Perenack and his team to anyone interested in cosmetic facial surgery!

Went in to get my buccal fat pads removed. I’ve always been very self-conscious about my cheeks (no matter my weight, I’ve always had chipmunk cheeks).
First off, the staff at his office was extremely accommodating and was a pleasure to work with.
Dr. Perenack came in for my consultation and told me the process he was going to use during my procedure. He went through my recovery with me and answered any question I had. His bedside manner was EXCELLENT. I went in for my follow up visit and everything looked great. I was only in pain for maybe a few hours until I got it under control. All other parts of the experience have been easy. I would recommend Dr. Perenack to anyone for any cosmetic procedure!
-Rhett
I had an otoplasty surgery done by Dr. Perenack himself and he could tell I was scared because it was my first surgery. He comforted me by showing me before and after pictures of other patients he has preformed this procedure on. That made me feel better. The staff was amazing! They have such an aesthetically pleasing office! Everything is clean. They offer mints and cold water to you while you wait. I was very happy with my whole experience! I honestly felt pampered. They take wonderful care of you here.

I have had several procedures with Dr. Perenack over the years. Laser Resurfacing for skin tightening and smoothing, fillers to strengthen my jawline and a hair transplant to re-establish my front hairline are some of my favorites. His evaluations are thorough and he is able to provide many before and after photos of his work. I always receive compliments regarding my skin and, thanks to Dr. Perenack’s skills, no one has guessed that I have had anything done or even my actual age. I moved out of Baton Rouge a year ago but still travel back versus going to anyone else. It is WORTH it! His results are impressive and he and his staff are always available to make sure the experience and recovery go well. He has always addressed any issues or concerns that I may have had before or after my procedures. Great bedside manner and great business ethics! Currently looking at dates for the Morpheus and Facetite with Dr. Perenack.
-Michael
I am so so happy with the results from my procedures. What's awesome is that the changes are not overwhelmingly noticeable; instead everything still looks natural, but now I have so much more confidence, especially when it comes my side profile. I wouldn't change anything. Dr. Perenack did an amazing job and was always so helpful and informative in every step of the process. Thank you Dr. Perenack!
-Summer
