Can this spray be used every day, and will it weigh the hair down? — The Doctor Health&Care Hair Spray Keratin + Arginine + Biotin "Maximum Energy" 150 ml

The spray is a leave-in product that fits into a daily routine: after washing your hair, before blow-drying, or during the day for a quick tidy-up of the lengths. Daily use is perfectly acceptable as long as you choose the right amount.

The silicone in the formula creates a thin smoothing film — this is what gives slip and reduces frizz. In moderate amounts it does not feel heavy, but if you apply too much or spray close to the roots, silicone build-up can over time make hair heavier and less voluminous.

Practical guidelines:

• Fine hair that quickly loses volume — start with the smallest amount and spray only on the lengths and ends, avoiding the roots.
• Porous, dry or coloured hair — tolerates the product better, as it absorbs the ingredients more readily and is less often weighed down.
• Long hair — you can apply a little more, concentrating on the mid-lengths and ends, where tangling and dryness are more pronounced.

If your hair starts to look heavier or duller with regular use, it is enough to take a break for a few days or to use a clarifying shampoo to remove the accumulated silicone.
