Aimed at people whose main hair concern is frizz and lack of manageability, particularly with medium to thick, coarse hair. KMS says it works for all hair types, so finer hair that frizzes can use it too.

It fits anyone who wants to avoid SLS/SLES sulfates and silicones in their shampoo. The 750 ml size is practical for salons, back-bar use or households going through shampoo quickly.

Frizz control starts in the shower. This shampoo cleanses with milder, SLS/SLES-free surfactants while a guar-based conditioning agent and hydrolyzed olive help leave hair detangled and smoother before any styling product goes on. For coarse or frizz-prone hair, starting with a shampoo that is not stripping means the rest of the All Smooth routine has less to correct.

1. Apply to wet hair and lather.
2. Rinse.
3. Repeat if necessary.
4. Follow with conditioner or treatment.

Pros

• Cleanses without SLS/SLES sulfates and without silicones.
• Detangles and smooths as it cleanses, which makes conditioning and styling easier afterwards.
• Available in two sizes, including a 750 ml salon-size bottle.

Cons

• It is a first step only; KMS recommends following with conditioner or treatment.
• Contains Sodium C14-16 Olefin Sulfonate, which some sulfate-free shoppers also choose to avoid.
• The 750 ml bottle may arrive in the earlier Tame Frizz packaging, as All Smooth is the renamed Tame Frizz range.
