Beauty Routine Workflow

Effective beauty and skincare routines start with knowing your hair and skin characteristics. Generic product advice fails because it doesn't account for your specific hair porosity, curl pattern, skin type, or UV exposure needs. These tools identify your individual characteristics first, then guide you to the right products and routines.

Identifying Your Hair Type and Porosity

The Hair Type Quiz identifies your hair pattern on the 1A–4C scale: straight (1A–1C), wavy (2A–2C), curly (3A–3C), and coily (4A–4C). Each type responds differently to products — curl patterns 3C and above benefit from leave-in conditioners and curl-defining creams that would weigh down straight hair. The Hair Porosity Quiz is often more important than curl pattern for product selection. Low porosity hair (scales lie flat, resist moisture absorption) does best with lightweight products and heat during conditioning. High porosity hair (damaged or naturally porous cuticles) absorbs moisture quickly but loses it just as fast — needs heavier sealants, protein treatments, and layered moisture. Normal porosity sits between and is the most forgiving.

Hair Color

The Hair Color Mixing Guide covers developer ratios for different lift levels (10-vol for tone-on-tone, 20-vol for 1–2 levels of lift, 30-vol for 3 levels, 40-vol for maximum lift), toner formulation for neutralizing brassy undertones, and color mixing ratios for custom shades. Fragrance concentration: the Fragrance Concentration Guide explains parfum (20–30% fragrance oil, 8+ hours), eau de parfum (15–20%, 5–8 hours), eau de toilette (5–15%, 3–5 hours), and eau de cologne (2–4%, 2–3 hours).

Skincare Routine Building

The Skincare Routine Builder sequences products in the correct application order: cleanser → toner → serum/treatment → moisturizer → SPF (morning) or sleep mask/oil (evening). It adjusts for skin type: oily skin avoids heavy oils and focuses on niacinamide and salicylic acid; dry skin prioritizes hyaluronic acid, ceramides, and occlusives; sensitive skin avoids fragrance, alcohol, and high-concentration actives. The Foundation Shade Finder identifies warm, cool, or neutral undertones from visual cues (vein color, how skin reacts to gold vs silver jewelry) and maps them to foundation shade families.

Sun Protection

SPF 30 blocks approximately 97% of UVB rays; SPF 50 blocks 98%. The difference is small in percentage but meaningful for extended exposure. The SPF Calculator estimates how long you can stay in the sun before burning, factoring in Fitzpatrick skin type (type I burns in 10 minutes unprotected; type V in 60–90 minutes) and the UV index. A type II person with 15 minutes of unprotected sun time wearing SPF 30 can stay out approximately 7.5 hours before burning. The Nail Shape Guide shows how round, square, oval, almond, coffin, and stiletto shapes complement different finger and hand proportions.

Frequently Asked Questions

What is the difference between hair type and hair porosity?

Hair type describes your curl pattern (straight, wavy, curly, coily on the 1A–4C scale). Hair porosity describes how well your hair cuticle absorbs and retains moisture. Both matter for product selection, but porosity often has a bigger impact on which products actually work. Two people with the same 3A curl pattern but different porosity need completely different conditioners and styling products.

What is the correct order to apply skincare products?

Apply products from thinnest to thickest consistency: cleanser → toner/essence → serum/treatment → eye cream → moisturizer → face oil (if using) → SPF (morning only). Water-based products go before oil-based ones. Actives like vitamin C and retinol go in the serum step — never mix them in the same routine as they can destabilize each other.

Is SPF 50 significantly better than SPF 30?

SPF 30 blocks 97% of UVB radiation; SPF 50 blocks 98%. The absolute difference is only 1%, but that extra 1% matters for extended outdoor exposure or those with photosensitive skin conditions. More important than SPF number is whether you apply enough (1/4 teaspoon for the face) and reapply every 2 hours when outdoors.

How do I find my foundation undertone?

Look at the veins on your inner wrist: blue or purple veins suggest cool undertones (look for foundations with pink or neutral bases); green veins suggest warm undertones (look for yellow or golden bases); blue-green suggests neutral undertones (most shades work). Also test: gold jewelry flattering = warm, silver = cool, both = neutral. The Foundation Shade Finder walks through these cues systematically.
