Photograph the part. Do not triple minoxidil because a blowout looked thinner in the brush.
Heat plus chemicals denature the shaft already on your head. Follicles under the skin follow telogen clocks after illness, not a same-day smoother. Pattern maps remain androgenetic until an exam. Related: heat-styling URL (tools without the keratin bottle). This is not medical advice.
Do not start finasteride from a salon Instagram. Breathing irritation in the salon is occupational health, not this millilitre.
Blistered scalp or painful clumps after a treatment is dermatology. This is not medical advice.

FAQ
Is a full brush after keratin telogen?
Often broken lengths. Telogen is months later. A patterned part needs an exam.
Raise foam after a smoother?
No. Intact dry scalp, carton only.
Is “formaldehyde-free” a hair-loss treatment?
Marketing language. Irritation still happens. Not a 5-ARI.
Same as heat-styling?
Cousin. This file is chemical smoothers plus heat. That file is tools.
