HH Simonsen Keratin Boost Keratin Filler, 250 ml
Intensive Keratin Repair for Shiny, Healthy-Looking Hair
HH Simonsen Keratin Boost is an intensive keratin filler designed for deep, targeted hair care when a regular conditioner isn’t enough. It helps restore keratin levels, strengthens the hair fiber, and delivers noticeably more smoothness and shine. The result: hair looks healthier, feels softer, and regains a vibrant, glossy finish.
Why choose Keratin Boost?
- Deep nourishment & care – intensely conditions hair when it feels dry, weakened, or depleted.
- Keratin level restoration – helps replenish lost keratin and reinforce the hair structure.
- Sleek, glossy hair – leaves a silky feel and helps visibly tame frizz and flyaways.
- Versatile use – ideal as a fast-acting intensive mask or as an added step for heat styling routines.
How to use
1) Used together with the Nourishing Styler hair straightener
Keratin Boost is specially developed to support keratin replenishment when used with the Nourishing Styler hair straightener. This combination helps the formula work more precisely, leaving hair smoother, healthier-looking, and more radiant.
2) As a quick rinse-out mask (2–4 min.)
- Wash hair and towel-dry until it’s damp but not dripping.
- Apply Keratin Boost through lengths and ends, distributing evenly.
- Leave on for 2–4 minutes.
- Rinse thoroughly.
- Finish your routine with a conditioner (use Keratin Boost before conditioner).
Best for
- Hair lacking vitality and shine.
- Weakened, dry, or damaged hair that needs more intensive care.
- Anyone looking to strengthen hair while improving smoothness and elasticity.
Result
With regular use, hair becomes visibly shinier, smoother, more manageable, and healthier-looking. Keratin Boost helps create the effect of well-cared-for, vibrant hair—both in everyday routines and before styling.
