Lesson 1Soothing and anti-inflammatory actives: panthenol, niacinamide, bisabolol for scalp tolerance and sensory benefitsHere we talk about calming and anti-swell actives that help scalp feel good in damaged hair care. You will learn about panthenol, niacinamide, bisabolol, and how they help block work, red marks, itch, and overall feel sense.

You will learn how they fill cuticle holes, cut soak, boost smooth, and help long-term hold against pull and chem stress.

You will learn how size, charge, and break degree hit going in, film make, strength, and balancing stiff with soft.

You will compare plant oils and made esters, get fat acid setups, go-in depth, and how they hit frizz, shine, and breaks.

You will compare sulfates and no-sulfate mixes, look at anionic, amphoteric, nonionic parts, and plan milder but good clean setups.

You will compare quick-gone and stay silicones, PVP/VA and plastics, and learn how films hit shine, frizz, heat guard, and build-up.

You will compare glycerin, glycols, hyaluronic acid, get water tie vs wet tired, and learn how weather and soak guide wet-keeper amounts.

You will learn how keepers, metal-ties, pH changers, and anti-air-breakers keep germ safe, steady, and cut more air harm.

You will study charge full, stick power, build-up, and how quats and polyquats hit comb ease, slip, full, and long hair feel.

You will learn key bits, their react paths, real fix limits, and how to mix them without shaking other actives.
