Is Frequency Shampoo safe for sensitive, acne-prone, or dry scalp and hair?

The shampoo's neutral pH and silicone-free base make it generally suitable for normal to dry scalps, but the presence of sodium laureth sulfate, fragrance and the allergenic fragrance component butylphenyl methylpropional can cause irritation for highly sensitive or acne-prone skin, so a patch test is recommended.

What benefits does panthenol provide in this shampoo formula?

Panthenol (pro-vitamin B5) penetrates the hair cuticle to retain moisture, improve elasticity and add shine, while also soothing the scalp and supporting a softer, more manageable hair texture.

How often should Frequency Shampoo be used and does it contain any controversial chemicals?

Designed for frequent use, the product can be applied 3-4 times per week or daily as suggested by its name, but users should be aware that it contains sodium laureth sulfate, a synthetic surfactant, fragrance, and three CI colorants, which are considered controversial by some consumers despite being approved for cosmetic use.

Product Insights

Frequency Shampoo is a 400 ml silicone-free shampoo formulated with a neutral pH for the scalp. Its blend of hydrolyzed keratin, panthenol, jojoba seed oil, and chamomile extract aims to strengthen the hair shaft, add moisture and soothe the scalp. However, the formula includes sodium laureth sulfate, fragrance and several synthetic colorants (CI 47005, CI 16035, CI 14700), which may irritate very sensitive skin or trigger allergies to butylphenyl methylpropional.

Comparative Analysis

Positioned as a daily-use, neutral-pH, silicone-free cleanser, Frequency Shampoo distinguishes itself from moisturizing or clarifying shampoos by combining strengthening agents like hydrolyzed keratin and panthenol with a gentle scalp-friendly pH.
