• Fine hair with a proportionally thinner cuticle tangles more readily than adult hair.
• Friction against car seats, pillows, hoods and the back of a sofa, all day.
• Wet hair is at its weakest and most extensible, and its cuticle scales are raised — which is exactly when most children's hair gets combed.
• Shed hairs wrap around neighbours, especially in curly and coily hair, forming knots that then tighten.
• Children move, so a comb catches at angles it would not on a still head.

A detangler deposits a cationic film — the same mechanism as Conditioner — that neutralises surface charge, lays the scales flat and lubricates the shaft.

• Section the hair. Four sections minimum on thick or curly hair.
• Start at the ends and work upward in short passes. Combing from the roots down drags every knot into a compacted mass at the ends, and that single error causes most of the pain and most of the breakage.
• Wide-tooth comb or fingers, never a fine comb on wet hair.
• Hold the section above where you are combing, so the pull is taken by your hand rather than the child's scalp. This is the difference between a routine and a battle.
• Damp, not soaking, for straight hair; damp with product for curly and coily.
• A knot that resists needs more product and more time, not more force.

• Fragrance-free where possible.
• "No tears" is a marketing phrase with no legal definition in the US or the EU. It describes low-sting testing, not an approval, and it does not mean a product will not irritate an eye.
• No essential oils on young children.
• A spray, which is hygienic because nothing returns to the bottle.
• Short ingredient lists.

Diluting conditioner with water in a spray bottle is a staple of curly-hair routines and works well. It also dilutes the preservative system, and a warm bathroom is a growth medium.

Make small amounts and use them within a few days. Do not keep a home-mixed spray for a month.

Cosmetic in the US — FDA primary category (01) baby products, overlapping with (06) hair preparations (non-coloring). No premarket approval, and no separate stricter safety standard for children's cosmetics than for adults'.

Under MoCRA, facilities register, products are listed, safety substantiation records must be held, and serious adverse events are reportable within 15 business days. The small-business exemption does not apply to products that regularly contact the mucous membrane of the eye, which a spray used near a child's face may.

In the EU, this is a leave-on product, so methylisothiazolinone is prohibited in it; preservatives come from the Annex V closed positive list of 60 entries; and cosmetics for children under three require specific attention in the safety assessment.

12 months after opening. Spray bottles are the most hygienic format because nothing returns to the reservoir.

Discard at cloudiness, separation or a change in smell. Home-diluted sprays: days, not months.
