Close, but not identical. Nourishing formulas focus on depositing oils, butters, and proteins (e.g., argan, shea, and keratin amino acids). Moisturising formulas focus on water-binding humectants (glycerin, hyaluronic acid, panthenol). Most modern bottles combine both, so labelling overlaps.

Yes, but choose lighter formulas. Argan- and hyaluronic acid-based options like Limitless M1 sit well on fine hair. Avoid heavy lanolin or butter-rich shampoos, which can weigh down the roots and leave fine hair flat after one or two washes.

Not always. Sulphates clean efficiently and are not damaging in small doses, but if your hair is colour-treated, curly or already very dry, a sulphate-free nourishing hair shampoo will hold moisture better between washes. Many of our top sellers, including 12 Reasons and E18HTEEN, are sulphate-free by default.

You can, but most dry hair does not need it. Two to four washes per week is the sweet spot for keeping the scalp clean without stripping the lengths. Daily users should look for explicitly mild formulas, such as Luxliss Keratin Daily Care, designed for daily use.

Limp roots, hair that feels coated, and a slow-to-dry texture after washing. If that sounds familiar, run a clarifying or scalp wash once a fortnight, then return to your nourishing routine. The fibre should feel soft, not slippery.
