What Happens If You Leave Purple Shampoo In Your Hair For An Hour?


The last thing that anyone who has a blonde dye job or bleaching done on their hair wants is to have brassy hair. And, unfortunately, you cannot avoid that from happening. Over time, no matter how much you protect your blonde hair, you will end up with brassy yellow tones that can ruin the look of your dyed hair. Even if you wear your hat to protect your hair from the sun’s UV rays or wear a swimming cap when you swim and use a heat protectant to prevent damage from using styling tools – your hair will over time become brassy.

That is why the remedy for that is purple shampoo if you have blonde hair. The purple neutralizes yellow colors since purple and yellow sit on opposite ends of the color wheel. Your stylist would give you instructions regarding how long to leave your purple shampoo in your hair if you plan to use it on a given day. You don’t usually leave it in for more than a half-hour, or 45 minutes at the most. What will happen if you leave the purple shampoo in your hair for an hour? Let’s talk about what to expect if you leave it sitting in your hair for too long!

What To Expect If You Leave Purple Shampoo In Your Hair For An Hour Or Longer

When you use purple pigments in brassy yellow colors, the stains will neutralize the yellow strands of hair, and it will no longer be that dull, brassy color. That is why a little bit of purple shampoo will help restore the beautiful blonde that you miss when the brassy yellow hair takes over. However, the trick is to leave the purple shampoo in the recommended timeframe or not deliver the results you want. That means if you end up leaving the purple shampoo in your hair for an hour or longer, you will end up with purple hair.

Too much of the purple pigment will no longer provide you with the neutralization that you want. As a result, you will have purple hair whether you like it or not! The same thing will happen if you use the purple shampoo too often, meaning more than once a week if you maintain your hair. You may be able to leave the shampoo in your hair for a little longer and more frequently than once a week if your hair has too much brassy yellow in it. That will be up to the stylist to make that recommendation. However, a rule of thumb is to use the purple shampoo once a week for no longer than 45 minutes, which goes for extreme cases. Or else, you will end up with lilac or violet-colored hues in your hair.

If you want to rock the purple hair appearance, then that is one thing. However, if you are using purple shampoo for neutralizing the brassy yellow strands, chances are you are not looking to add some purple hues to your hair. And if you wanted to do that anyway, using too much purple shampoo is not the way to go for it.

Too Much Purple Shampoo Can Also Dry Out Your Hair

If it was not bad enough that leaving purple shampoo in your hair for too long would cause it to turn purple, another problem with leaving purple shampoo in your hair is that it will dry your hair out. That is because there are harsh elements in the shampoo that will strip away your sebum, and that will leave you with a dry and itchy scalp, in addition to it appearing dull and frizzy. Therefore, as you see, if you leave the purple shampoo in for very long such as an hour or longer, then you will end up with very dried out hair too.

What Can You Do To Reverse The Effects Of Leaving Purple Shampoo In Your Hair For Too Long?

If you do not stick to the recommended timeframe of using purple shampoo, you will end up with purple and dried-out hair. Fortunately, there is a remedy for this, and you can use clarifying shampoo. You can also use color-safe shampoos as well. The best thing to do is to use a clarifying shampoo one time you shower, and then you can use a color-safe shampoo for another time you shower. Therefore, it is ideal to alternate. Make sure you add some conditioner, too, so you can restore the moisture and natural oils in your hair. You can also mix a color-safe shampoo with purple shampoo when you plan to use it, so you don’t end up with too much purple pigment. You will have to be patient as far as waiting for the purple hues to leave your hair and for it to improve your hair’s appearance. Over time, you will restore your lovely hair!
