If you leave purple shampoo on for too long, you may find yourself with a little lilac hue. This color is not permanent and is more likely to happen if you have very light blonde hair or if your hair is dry and damaged. To remove the purple hue, switch to regular shampoo for your next few washes.
Hair that's extremely brassy or has been color-treated (e.g., dyed blonde hair) may need extra time to absorb the purple pigments. To correct this, leave the shampoo on for up to 15 minutes. For platinum blonde, gray, or silver hair, you can leave the purple shampoo on for up to half an hour.

In short: No, you shouldn't put purple shampoo on dry hair. While it's true that dry hair will absorb more pigment, it's also uneven in its absorption. For most if not all of us—blonde or not—the ends tend to be drier and more porous than the rest of our hair.
When you leave the conditioner in your hair overnight, your hair may get brittle, dull, frizzy, or tangled. Not to mention, the excess water can make it look dull, attract dirt and dust, give it a gummy texture, create split ends, and cause breakage.
Unless you have white hair or gray hair, you shouldn't leave the purple shampoo on for longer than 15 minutes at a time. If you're already leaving the shampoo on for less than 15 minutes and you're noticing a purple tone, then try leaving the product on for even less time.
The continuous stress of wetting and drying can even lead to breakage. Sleeping with deep conditioner on the hair puts you at risk of damage in the form of hygral fatigue, because there is too much moisture penetrating the hair shaft.
Purple shampoo is for already bleached hair, so if you're hoping to lighten brown hair with purple shampoo, you'll be disappointed. This is all down to the fact that purple shampoo isn't lightening. Instead, it brightens blondes by canceling out yellow tones, which just happen to be opposite purple on the color wheel.
So what is the best way to use purple shampoo? If you want to use a purple shampoo, Maine recommends “soaking your hair with water and even adding a little conditioner on your ends” beforehand, to prevent the porous tips from absorbing too much pigment.
It's important to note that the pigment in purple shampoo isn't a lightener or hair dye but a gentle toner that works overtime. So it can't darken your hair or make it any lighter. For this reason, if your hair tone is too dark, it won't make it any brighter.
Well, unlike its shampoo counterpart which acts as a toning agent to neutralize brassiness, the conditioner does the job of nourishing hair after toning. A lot of purple conditioners are also pigmented with a bluish/purple tint to help tone hair even further after your shampoo.
Zoe's answer: Leaving purple shampoo in your hair for longer than the recommended time is not always a good idea. The longer you leave it, the more pigments will be deposited on your hair and they could even stain it permanently.
Not enough purple shampoo won't tone your brassiness, while using too much too often will turn your hair ashy or purple.

Doss warns that there is such a thing as too much purple. “When you eliminate too much yellow, it visually ends up darker and a lot of people don't want it to look darker,” she says.
Purple does not cancel out orange shades to the extent that it would cancel out yellow tones, being that they are not complementary colors.
How Do Purple Conditioners Work? Purple shampoos and conditioners use violet pigments to help neutralize brassiness and achieve a cleaner, whiter tone. Purple is the opposite color of yellow on the color wheel, so if your hair starts turning brassy, purple shampoo and conditioner will help cancel out warm undertones.
For untreated, naturally blonde hair, you'll only want to leave the shampoo on for 2 to 3 minutes before rinsing. Hair that's extremely brassy or has been color-treated (e.g., dyed blonde hair) may need extra time to absorb the purple pigments. To correct this, leave the shampoo on for up to 15 minutes.
The purple-tinted conditioner is for all shades of color-treated blonde, highlighted and lightened hair. By further strengthening strands and brightening hair color, it enhances the effects of both Strength Cure Blonde Shampoo and Miracle Filler Treatment.
Doss warns that there is such a thing as too much purple. “When you eliminate too much yellow, it visually ends up darker and a lot of people don't want it to look darker,” she says. “So if you wash your hair twice a week, use the purple shampoo only once a week to keep the hair bright but not yellow.”
