Getting rid of seborrheic dermatitis is easier than you think with Selsun Blue.

Selsun Blue’s active ingredient is one percent selenium sulfide. Selsun Blue is a popular dandruff shampoo, and any similar shampoo with this active ingredient should be just as effective at treating seborrheic dermatitis.

I was diagnosed with seborrheic dermatitis some years ago. My doctor told me to just put Selsun Blue on the patches, then rinse.

I wonder how many people, who struggle with seborrheic dermatitis, have tried Selsun Blue or another shampoo with the one percent selenium sulfide. Maybe I’m an exception, but the stuff works like a charm.

I put my index finger to the bottle’s opening and tip it, getting a good gob on my finger. I then smear the shampoo on my skin, giving it a thick coat.

This is primarily on the sides of my nose, including where the nose has a crease.

It’s also on the front lower part of my nose, and sometimes on my forehead, between but above my eyebrows.

There’ve been times when the seborrheic dermatitis appeared below my eyebrows, and I dabbed the shampoo there as well.

There’s no reason to wait any length of time before rinsing. After you apply the shampoo, just rinse with water.

Any residue can be wiped away with a few Q-tip swabs held together. There’s no need to rub. Be gentle.

A wet sponge will also work on flatter areas. I’ll dab with the sponge on the front of my nose and on my forehead.

I’ll then splash water on my face. Residue is removed with the Q-tips.

I’ve noticed an improvent within 24 hours, and a complete elimination in about three days or less.

However, what typically happens is that I get lazy and stop applying the Selsun Blue.

Invariably, the seborrheic dermatitis returns. Sometimes I’ll let it go several days, but it isn’t long before I’m forced to apply the shampoo again.

If I applied the Selsun Blue every day, or maybe even every other day, this would prevent flare-ups of the seborrheic dermatitis.

But let’s face it: It’s a drudgery to have to do this every single day or even every other day.

Sometimes I forget. Sometimes I remember and just decide to skip it, because I know that when the seborrheic dermatitis flares up again, I could make it disappear within three days by just putting the shampoo on it.

The reason the active ingredient in this shampoo is so effective is because the process that leads to seborrheic dermatitis is the same process that leads to scalp itchiness and dandruff — that’s what my doctor told me.
