The Color-Depositing Mask (The In-Between Hero)<\/span><\/strong><\/h3>\n<p class=\"ng-star-inserted\"><span class=\"ng-star-inserted\">These are deep conditioning treatments laced with semi-permanent pigment.<\/span><\/p>\n<ul class=\"ng-star-inserted\">\n<li class=\"ng-star-inserted\">\n<p class=\"ng-star-inserted\"><strong class=\"ng-star-inserted\"><span class=\"ng-star-inserted\">How it works:<\/span><\/strong><span class=\"ng-star-inserted\">\u00a0It restores moisture while replenishing lost pigment on the hair\u2019s surface.<\/span><\/p>\n<\/li>\n<li class=\"ng-star-inserted\">\n<p class=\"ng-star-inserted\"><strong class=\"ng-star-inserted\"><span class=\"ng-star-inserted\">The Benefit:<\/span><\/strong><span class=\"ng-star-inserted\">\u00a0You can push your permanent dye appointment back by 2\u20133 weeks simply by using a depositing mask at home.

Hair Loss Resist &amp; Strengthening Shampoos<\/span><\/strong><\/h3>\n<p class=\"ng-star-inserted\"><span class=\"ng-star-inserted\">Chemical processing can weaken the follicle, leading to shedding.

If you used permanent dye or bleach,\u00a0<\/span><strong class=\"ng-star-inserted\"><span class=\"ng-star-inserted\">no<\/span><\/strong><span class=\"ng-star-inserted\">. Your hair cuticle is currently wide open and vulnerable. Applying more chemical processing immediately can lead to severe breakage. Wait at least 2 weeks and use deep conditioning masks in the meantime.<\/span><\/p>\n<p class=\"ng-star-inserted\"><strong class=\"ng-star-inserted\"><span class=\"ng-star-inserted\">Q: Does washing my hair less make the color last longer?<\/span><\/strong><br class=\"ng-star-inserted\" \/><strong class=\"ng-star-inserted\"><span class=\"ng-star-inserted\">A:<\/span><\/strong><span class=\"ng-star-inserted\">\u00a0Yes. Water is the #1 enemy of hair color. Washing less frequently allows your natural oils to protect the cuticle. When you do wash, use cool water and a sulfate-free, strengthening shampoo.<\/span><\/p>\n<p class=\"ng-star-inserted\"><strong class=\"ng-star-inserted\"><span class=\"ng-star-inserted\">Q: Is it safer to dye dirty hair?<\/span><\/strong><br class=\"ng-star-inserted\" \/><strong class=\"ng-star-inserted\"><span class=\"ng-star-inserted\">A:<\/span><\/strong><span class=\"ng-star-inserted\">\u00a0Generally, yes. The natural oils on your scalp act as a protective barrier against chemical irritation. It won&#8217;t stop hair damage, but it will save your scalp from stinging.<\/span><\/p>\n<hr class=\"ng-star-inserted\" \/>","protected":false},"excerpt":{"rendered":"<p>As the seasons change, the urge to switch up your look often follows.
