Global Keratin GK HAIR pH+ Pre-Treatment Clarifying Shampoo - Deep

In this review the Global Keratin GK HAIR pH+ Pre-Treatment Clarifying Shampoo is judged on how well it prepares hair for professional taming and straightening while also serving as a weekly deep-cleansing option. The bottom line: this clarifying shampoo is best for people who need a thorough, cuticle-opening wash before chemical or smoothing services and for anyone looking to remove heavy buildup once a week. It stands out because its formula combines aloe vera and pro vitamins to soothe the hair while stripping residues, though those with very dry scalps should use it sparingly.

Key Features

• Pre-treatment formula: Designed to open hair cuticles and remove impurities so hair taming and straightening treatments adhere and work more predictably.
• Deep cleansing action: A clarifying blend removes product buildup and excess oils from the inside out, leaving hair ready for the next step in a salon process.
• Nourishing ingredients: Aloe vera and pro vitamins are included to gently soothe and help strengthen hair from the roots during the clarifying process.
• Weekly use guidance: Formulated to be used only once a week to refresh the hair and make regular shampoos more effective without daily stripping.
• Suitable for deadlocks and treated hair prep: The purifying properties make it useful for preparing textured or locked hair for treatment when a deep clean is required.

Who It's For

The shampoo is aimed at people preparing for professional hair taming, straightening, or keratin treatments who need cuticle-opening cleansing to ensure even processing. It also suits those who use heavy styling products or oils and want an occasional deep-clean to restore shine and manageability.

Not recommended for daily use or for people with persistently dry, sensitive scalps who react to strong clarifiers; such users should look for a gentler, moisturizing daily shampoo and reserve this product for weekly or pre-treatment use only.
