Is hair loss a symptom or a diagnosis?🤔

10/02/2025

Shock Hair Loss is not an official medical diagnosis; it’s a descriptive phrase used to explain a type of temporary shedding that sometimes occurs after a hair transplant.

There are 2 types of medically recognized shedding:
1. Anagen Effluvium (transplanted hair) - when donor hairs go through a stressful process, this can cause the hair shaft to shed, even though the follicle is still alive & healthy. This is temporary, usually within the first 2-4 weeks.
2. Telogen Effluvium (existing hair) - surgery can act as a stressor, triggering your existing hair follicles to prematurely shed 2-3 months after surgery. This is temporary, and they too return within a few months.

Can Shock Hair Loss be Prevented?
While some shedding is unavoidable, the severity can be reduced:
* Choose an Experienced Surgeon
* Gentle Handling of Grafts
* Use of Minoxidil
* Patience & Reassurance

Shock Loss after a surgery is normal, temporary & usually nothing to worry about - it’s simply your hair follicles responding to the stress of surgery. The end result of fuller & natural-looking hair is worth the wait.

Choose Your Doctor Carefully - Hair Transplant Surgery is Real Surgery.

The hair has to come from somewhere right?

Male AND female pattern hair loss happens thanks to genetics & the hormone DHT (Dihydrotestosterone). The hair on the top and front of your head is very sensitive to DHT, which is why it thins. But the sides & back? Those hairs are naturally resistant.

Think of those areas as your personal "hair bank". During a transplant, I carefully move those healthy DHT-resistant hairs to where you need them most.

The best part? The key is their survivability. This means that they will continue to grow for the long haul once transplanted in the proper areas.

Preserving, placing, and encouraging the new hair growth is one of the key components of my surgeries. I only use techniques & technologies that ensure hair grafts survive and thrive without damage or depletion, to provide a naturally restored head of hair.

Our hair grows in a natural cycle with four distinct phases: Anagen (growth phase), Catagen (transition phase), Telogen (resting phase), and the Exogen (shedding phase). This cycle repeats continuously, but certain factors can disrupt it at any stage, leading to hair thinning or loss.

One of the most common disruptors is Androgenic Alopecia, which is also known as male/female pattern hair loss, as this condition affects both men and women. This disruptor is characterized by the gradual shortening of the anagen phase, which means the hair doesn't grow as long. Additionally, it involves the miniaturization of hair follicles, resulting in thinner, shorter, and less pigmented hairs. Ultimately, many follicles stop producing visible hair altogether.

While genetics plays the major role in androgenic alopecia, hormones, age, and lifestyle factors like stress, nutrition, and health can all influence its progression.

If you’re experiencing hair thinning or loss, understanding these underlying mechanisms is the first step toward effective treatment.

If you’ve noticed your hair thinning or shedding more than usual, you may be feeling worried, frustrated, or even embarrassed. Please know this: you are not alone.

Millions of men and women experience hair loss, and while the causes can vary, the most important thing to remember is that there is something that can be done.

With today’s advanced treatments—from medications to surgical options like FUE & FUT hair transplants, some solutions can help restore not only your hair, but your confidence.

As a board-certified dermatologist, formally trained in the art and science of hair loss & hair restoration, my mission is to guide you through this journey with compassion, expertise, factual education, and proven results.

Hair loss does not define you. And with the right plan, you don’t have to face it alone.

When it comes to hair transplants, not all methods are created equal. With over 20 years of experience, I’ve developed a proven approach that prioritizes both science and artistry: The McAndrews Method.

Here’s what makes it different:

1️⃣ Natural & Undetectable Results – Your transplant should blend seamlessly with your natural hair, with a natural-looking hairline.
2️⃣ Maximum Growth & Survival – By focusing on precision, we ensure the highest rates of hair graft survival for long-lasting results.
3️⃣ Beauty Now & Later – The design of your transplant is planned not just for today, but for how it will look later as you continue to age.
4️⃣ Conservative Technique, Incredible Results – We focus on preserving donor hair while delivering transformative, yet natural outcomes.

The McAndrews Method isn’t just about restoring hair—it’s about restoring confidence with results that are timeless, natural, and virtually undetectable.

When you trust your hair to an expert, you deserve nothing less than a method that works for life.

Hair loss isn’t just a men’s issue; millions of women are affected, too. One of the most common causes is Female Pattern Hair Loss (FPHL).

Female Pattern Hair Loss often begins in your 40s, 50s, or 60s. It is a progressive condition, meaning that once it starts, it can continue. The good news? It IS treatable.

Topical solutions like minoxidil are often used. Once a long-used solution for male pattern hair loss, the FDA has approved this non-prescription treatment for women. Today, it is the most recommended treatment for Female Pattern Hair Loss.

Prescription medications such as spironolactone, which is a diuretic, can also be used for Female Pattern Hair Loss. It is a common treatment because it can help restore hair growth and prevent hair loss from worsening.

While these two options for treatment only cover the surface of treatments that are available, researchers are still looking for other treatment options for FPHL. Treatments such as Platelet-rich plasma therapy, stem cells, and different supplements are being researched to fully understand safer and effective treatments.

The most important step? Consult with an experienced dermatologist specializing in hair loss & hair restoration. A personalized treatment plan gives you the best chance at slowing progression and restoring confidence.

One of the most common questions I hear is: “Can I drink alcohol after my procedure?”

The short answer? No! Trust me, I get it, you just had a big surgery, and it can be tempting to have a drink, but in order to get the best results, it is best to completely avoid alcohol.

Here’s why avoiding alcohol is important for your recovery:

❌ Slower & poorer wound healing – alcohol interferes with your body’s natural healing process.

❌ Thinning of the blood – which can increase bleeding risks during recovery.

❌ Increased swelling – making recovery more uncomfortable and potentially affecting results.

By following post-procedure care instructions closely, you give your new grafts the best chance to survive and thrive.

Did you know that over 80 million people in the United States are affected by hair loss each year?

In our country alone, over 80 million people experience hair loss. While the causes can vary from genetic factors to lifestyle choices, there's one thing that makes a significant difference: the right treatment plan.

Hair loss is not a "one size fits all" which means that every patient's journey is going to be unique, which is why working with a board-certified Dermatologist who specializes in hair loss & hair restoration is key to achieving natural, lasting results.
