What's the best way to use this shampoo in a routine with conditioner or mask?

Because this shampoo is formulated to be gentle and lipid-friendly, it works best as the first step in a two- or three-step routine. Concentrate the shampoo on the scalp and roots — that's where sebum, sweat and product residue accumulate. The foam that runs down during rinsing is enough to cleanse the mid-lengths and ends without over-drying them.

Follow every wash with a conditioner on the lower two-thirds of the hair. The shampoo's oils (macadamia, argan) prep the cuticle by reducing inter-fibre friction, so the conditioner's cationic agents can adsorb more evenly and seal the surface. Leave the conditioner on for 2–3 minutes while you finish your shower, then rinse with cool water to help the cuticle lie flat.

If your hair is long, bleached, permed or heat-styled frequently, add a deep mask once a week in place of conditioner. Apply generously to towel-dried mid-lengths and ends, leave 10–15 minutes, then rinse. The shampoo's gentle base won't counteract the mask's richer oils and butters. For scalp sensitivity, introduce the shampoo first, use it for a week, then add the conditioner — this helps identify any reaction to a specific product.

Store the bottle upright, cap closed, away from direct sunlight. The 400 ml size typically lasts 2–3 months with shoulder-length hair washed 2–3 times weekly.
