About Hair Treatment
Review Product Labels
Read the ingredient list on the bottle. Look for sulfates, parabens, or harsh alcohols. These dry out your ends. Ask if the brand matches your hair type. Curly hair needs moisture. Straight hair needs volume. Wrong ingredients cause frizz within 48 hours. Check for vegan or cruelty-free options too.
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.
Check Water Resistance
Ask if the treatment survives swimming or rain. Some bonds break upon water contact. Chlorine strips color and protein. If you swim, demand a waterproof sealant. Untreated hair fades faster in pools. You might need a rinse before entering the water. Skip this step and your scalp itches.
Compare Final Quotes
Pricing varies by hair density and length. Long hair costs more due to product volume. Thick strands require more chemical processing. Ask for a written estimate before starting. Compare local quotes. Keep the receipt for warranty work. Do not accept verbal guesses. Price changes happen if hair is thicker than estimated. Get clarity on extra strands.
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.
Prep Your Hair Properly
Do not wash your hair 24 hours before coloring. Natural oils protect the scalp. Avoid product buildup for perms. Bring your brush if you cut at home. Wear dark clothing to protect fabric. Check for existing product mixes. Some serums react badly with ammonia. Mention oils used at home. This prevents foaming during application.
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.
Inspect Product Ingredients
Keratin treatments use formaldehyde or alternatives. Ask for the ingredient label. Some formulas smell strongly of vinegar. That indicates curing agents. Ensure the product suits your hair type. Dry hair needs extra bond repair. Weaker strands need lighter formula. Ask for samples. Do not apply unknown chemicals to your scalp without checking for allergy.
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.
Track Recovery Period
After straightening, avoid washing for 72 hours. Dry hair sets the bond. Do not clip pulls or tight styles for 48 hours. This prevents new dents. Your hairline is vulnerable during curing. Sleep on silk if possible. Avoid chlorine pools for 10 days. Salt water strips moisture. Wait a full day before heat styling after any chemical service.
