Here's a little @Olaplex tip for you guys to add your arsenal...if you're performing an on the scalp retouch lightening service you can simultaneously apply a stand alone treatment to the rest of the previously lightened mids/ends while the scalp area is processing. Sooo apply lightener to the new growth area starting at the nape working your way forward to the front hairline. Once that's applied mix your standalone @olaplex #1 and water to everything else. Allow to process to desired level rins
