Straight Razor Request on Warfarin

Mr. Alvarez, 68, requests a traditional straight-razor shave with hot towels before his granddaughter's wedding. He mentions he takes warfarin and that his last INR was 2.8. He also takes a daily aspirin and has pseudofolliculitis barbae on his neck, with several small bumps and one healing ingrown hair. He had a hip replacement eight months ago and says he is “not worried about a little nick.” He wants the closest shave possible and asks you to go “against the grain twice.” The shop has a straight razor, disposable blades, clippers, and a hot towel warmer. He has 25 minutes. He has already had one glass of champagne and is flushed. He signs a general consent form that does not mention blood thinners.

1. Identify the risk factors and decide whether to perform the straight-razor shave. Explain your reasoning.

Read the worked answer

The risk factors are significant: warfarin with a recent INR of 2.8, daily aspirin, pseudofolliculitis with open or healing bumps, a recent hip replacement, alcohol and flushing, and a request to shave against the grain twice. Warfarin and aspirin reduce clotting, so even a small razor nick can bleed longer than expected. Pseudofolliculitis means the skin is already inflamed and broken, which increases infection risk and makes a close razor pass more likely to cut. Going against the grain twice multiplies microtrauma.

The champagne and flushing are additional concerns because they can be associated with vasodilation and reduced coordination, and the client may not judge his own risk well. A general consent form that does not mention blood thinners is inadequate for this conversation.

My decision is not to perform a straight-razor shave, and not to go against the grain twice. The risk of prolonged bleeding, infection, and a poor healing outcome outweighs the closeness of the shave. I would explain the reasoning and offer a safer alternative or a referral for medical clearance.

2. What service can you safely offer, and what would you say to obtain informed consent?

Read the worked answer

I can offer a clipper shave with a guard, using a fresh blade and light pressure, avoiding the inflamed neck bumps. I would use a cool or comfortably warm towel rather than a hot towel, because heat increases blood flow and may increase bleeding risk, especially with alcohol and flushing. I would not use a straight razor, and I would not shave against the grain.

I would say: “Because you take warfarin and aspirin and have inflamed bumps on your neck, a straight-razor shave against the grain could cause prolonged bleeding or infection. I can do a clipper shave with a guard and avoid the bumps, or you can see your doctor for clearance before a razor shave. Which would you prefer?” I would document his choice and the risks discussed.

If he insists on the straight razor, I would decline rather than proceed. Informed consent is not just a signature; it requires capacity, a clear explanation, and a real alternative. The general consent form should be supplemented with a note about the blood thinner and the service modification.

3. If a nick occurs despite precautions, what do you do?

Read the worked answer

I would stop immediately, put on clean gloves if not already wearing them, and apply firm pressure with clean gauze for several minutes. I would not use a contaminated towel or keep shaving over the area. Once bleeding is controlled, I would clean the area gently and apply an appropriate first-aid dressing. Because the client is anticoagulated, I would advise him to seek medical attention if bleeding does not stop promptly, if it is heavy, or if he feels dizzy.

I would dispose of the gauze properly, clean and disinfect the chair and any tools that contacted blood, and change gloves. If the clipper or razor contacted blood, it would be cleaned and disinfected before reuse; disposable blades would go into a sharps container. I would document the time, the location of the nick, the first-aid steps, and the advice given.

The reasoning is that an anticoagulated client may bleed more than expected, and a small nick can become a larger problem. The barber's job is first aid and referral, not medical treatment.
