Step 11 - Keep away from Cigarette Smoke.
The chemicals in cigarette smoke (formaldehyde, arsenic, DDT, tar, hydrogen cyanide...) are horrible to hair. Plus having smoke-smelling hair means daily hair washing, so damaging your hair even more. Keep away from cigarette smoke and avoid spending time in rooms and cars where smoking has happened recently, as the toxic chemical particles linger on in soft furnishings.
