Use 1–3 pumps of hair serum: short 1 pea, medium 2 peas, long or thick 3–5—on damp mids-to-ends, not roots.

Most people need 1–2 serums per routine; layer up to 3 only if formulas target different needs and stay water-to-oil, thinnest to thickest.

For most hair, start with a nickel-size puddle (about 2–3 mL); very long or dense curls may need 5–10 mL, added in small passes as you cleanse.

For hair serum, start with 1–2 pea-size drops for fine hair, 2–3 for medium, and 3–4 for thick or long lengths, adjusting to avoid greasiness.

For shampoo use, start with 10–15 mL for short hair, 20–25 mL for medium, and 30–40 mL for long; adjust for thickness and oil level.

For dry hair, start with 1–2 teaspoons of shampoo (2–4 pumps) and adjust by length, thickness, and buildup to avoid stripping moisture.

Use 2–3 mL for most hair; short or fine need 1–2 mL, and long, thick, or oily often need 3–5 mL—target the scalp and adjust by lather.

Most serology tests cost $30–$200 before insurance; the price depends on the test type, lab, and any draw, visit, or facility fees.
