Ask the Dermatologist: Men’s Hair Loss & Skincare

Posted on: October 28th, 2019 by Shany Batbold

Men and women can experience the same basic dermatological issues. However, there are certain challenges that men face more often or with far greater intensity. California Skin Institute’s Dr. Jennifer Sorrell, a triple board-certified dermatologist, gives advice on questions that men commonly have about hair loss and skincare.

Q:        I’ve noticed acne appearing on my chest and back, especially when I’m more active or exercising a lot. What gives?

A:        Acne can definitely be more active when you’re sweating more, whether due to exercise, warm weather or increased physical activity. If you have a delay between sweating and taking a shower, the sweat can promote clogged pores and bacteria, leading to flares.

I suggest using a cleansing wipe to clean the acne-prone areas as soon as you complete your activity. Keep this in your gym bag for easy accessibility. A benzoyl peroxide wash is another over-the-counter option for mild acne on the chest and back. Look for one containing between 3-5% benzoyl peroxide, and use it daily in the shower. I recommend CSI Creamy BP Wash. This active ingredient does bleach linens, so use a white washcloth and towel.

If your acne is deeper and more severe, see your board-certified dermatologist to customize an effective treatment plan for you.


Q:        I like to keep my face clean-shaven, but I get lots of ingrown hairs and tiny bumps from shaving. How can I treat this?

A:        This condition is called pseudofolliculitis barbae, and can be very frustrating. The hairs in the mustache and beard distribution tend to be coarser, with a higher likelihood of turning back in on themselves. This can lead to an ingrown hair that becomes inflamed. Complications can include a dark mark left behind after the inflammation has resolved, as well as keloid or thickened scarring.

I recommend washing once daily with an exfoliating glycolic-acid product, like CSI’s Glycolic Gentle Cleanser, to help keep hair follicles unblocked.  Also use a single-blade disposable razor or electric razor, and shave with the grain of the hair rather than against it. Using a moisturizing shaving cream can also help. Prescription-strength options include a topical retinoid like Retin-A to exfoliate the skin and a bleaching cream to lighten dark spots. If you like the idea of being clean shaven all the time, laser hair removal can be a great way to eliminate the source of the problem.


Q:        I really enjoy spending time outdoors, and am having trouble finding a sunscreen that works for me. Any suggestions?

A:         Outdoor adventures are amazing and fun for sport and relaxation. Being vigilant with sun protection is essential to help prevent skin cancer and premature aging. Ideally, a sunscreen will provide broad-spectrum protection against both UVA and UVB rays.

I recommend a sunscreen containing zinc oxide. This active ingredient helps physically block a broad spectrum of the sunlight, yet is gentle on sensitive skin. Ideally, go with a water-resistant lotion sunscreen for first application. Favorites include EltaMD UV Pure and Blue Lizard Sensitive Mineral Sunscreen. While a spray is convenient, it is important that you apply enough of the sunscreen and also rub it in. I recommend starting with a lotion sunscreen for your first application and reserving a non-aerosol spray for reapplications. Good zinc oxide-based sprays are CSI Sheer Physical Sunscreen SPF50+ and Beautycounter’s Countersun Mineral Sunscreen Mist SPF30. Zealios Sun Barrier SPF45 cream contains a small amount of chemical sunscreen, in addition to zinc oxide, but it is a favorite for runners. No matter which sunscreen you choose, remember to reapply often throughout the day!


Q:        I feel like my hair is thinning and I have less hair at the top of my scalp. What can I do?

A:        This sounds like male pattern hair loss. It often begins with hair receding at the temples as well as thinning and falling out on the top (vertex) of the scalp. In some patients, it can start as early as adolescence.

A good first step is often to use minoxidil (Rogaine). This over-the-counter topical medication has been found to be helpful in preventing additional hair loss and, in some cases, regrowing hair. I recommend the 5% concentration, which comes in a solution and foam vehicle. When applied 1-2 times daily to the affected area, you should start to see results — after some possible initial shedding — in about 2-3 months. There are also some shampoos that are helpful for thinning hair, including NIOXIN and Paul Mitchell’s Scalp Care Anti-Thinning Shampoo.

If you’re experiencing more severe hair loss or desire aggressive treatment, consider the oral medicine called finasteride (Propecia). You’ll need an appointment for a prescription from your dermatologist, who will also discuss some important side effects with you. A newer treatment showing some promising results is called PRP. It involves injecting a concentrated sample of your own blood plasma into thinning areas to promote hair growth. PRP is typically performed monthly for four treatments, then switches to 2-3 times per year for maintenance. Your best plan of attack is to work with your board-certified dermatologist to come up with a custom-tailored treatment plan!
