About Hair Treatment
Diagnose Hair Health First
Your stylist should check scalp health before any treatment. Look for signs of dandruff, oil buildup, or breakage. Ask if your hair needs a keratin repair bond or just a wash cut. Untreated breakage weakens the structure and affects results. A visual inspection is non-negotiable. If they skip that, walk away. You need a baseline. Without it, costs rise later.
Identify Damage Triggers
Root gap appears when regrowth is visible. Your stylist should color 3 mm of new growth. Too much product damages old strands. Overlapping causes brittleness. Your mid-lengths feel like straw. They snap under tension. Mention this during booking. Your stylist lowers the developer volume. This saves your cuticle layer and prevents breakage at the crown.
Understand Washing Rules
Many treatments require 48 hours without washing. Shampoo strips the new chemical structure. Use sulfate-free shampoo only. Wash gently. Do not rub your scalp. Massage lightly. This preserves the treatment layer. Breaking this rule reduces effectiveness by half. Your hair feels dry soon.
Understand Tint Duration
Fresh tint lasts 4 to 6 weeks before fading. Semi-permanent color washes out in 5 to 8 washes. Permanent tone requires reapplication every 4 to 6 weeks to cover roots. Your stylist explains pigment depth. Lighter shades fade faster. Ensure the product grade matches your goal. Budget for reapplication every 4 to 6 weeks.
Verify Professional Credentials
Your provider should show valid licenses. Ask how long they have worked in the field. Certification ensures safety training. Check their studio reviews online. Do not trust word of mouth only. Confirm their knowledge of patch testing. New chemicals start with a small 24 hour test behind your ear. Do not skip the test if you have sensitive skin.
Evaluate Hair Porosity
Porosity measures how well hair absorbs water. High porosity absorbs too much. Low porosity resists it. A good stylist tests a strand first. They adjust product strength accordingly. Wrong strength leads to mushy hairs or no change. Tell them about previous bleaching or heat damage.
Safe Chemical Strengths
Perm rods use 9 to 12 size cylinders. Thinner rods mean 9 to 12 hour processing for weak hair. Stronger chemicals cure frizz but damage the inner shaft. Ask about neutralizer time. It should be 10 to 15 minutes. Too short means weak curls. Too long means dry brittle results. Your curtain hair should check mid-treatment.
Maintain Results At Home
Use color-safe shampoo to extend treatment life. Reduce washing to 2 to 3 times per week. Dry heat melts keratin bonds quickly. Using a ceramic dryer helps preserve shine. Your dryer should stay 5 cm from the scalp. Move it constantly. Static electricity lifts cuticles. Apply leave-in conditioner only to wet ends. Dry strands absorb too much moisture and swell.
Inspect Tool Temperature
Ask about the heat plate settings. Most keratin smoothers work at 230 degrees Celsius. Too hot burns the cuticle. Too cold fails to lock the protein. You will see frizz return in 1 week. Request a test section first. Feel the plate temperature visually. Safe gear protects your cap.
Set Realistic Timing
A full treatment takes 90 to 120 minutes. Coloring add-ons add 30 to 45 minutes. Keratin smoothing requires 100 to 140 minutes. Your schedule helps them plan products. Rushing leads to uneven absorption. Ask for an exact arrival time. If they overbook, you wait longer. Verify they start with your shampoo. Verify before you sit down.
