Your stylist at Honeys Hair & Beauty in Taunton can recommend the perfect application technique and show you how to layer this treatment into your home care routine for maximum impact.

Frequently Asked Questions

How often should I use the Long & Strong Leave-in Treatment?
Apply to clean, towel-dried hair after every wash for best results. It's gentle enough for daily use and works as part of your regular styling routine without weighing hair down.
Will this treatment make my hair greasy or heavy?
No, the formula is lightweight and fast-absorbing. It won't leave residue or weigh down fine hair, making it suitable for all hair types including fine or oily hair.
How long before I see results?
Clinical studies show increased density and a 94% reduction in hair loss after 60 days of consistent use. Some clients notice hair feels stronger and more manageable within the first few weeks.
Can I use this with heat styling tools?
Yes, absolutely. The treatment provides thermal protection up to 450°F, making it an excellent heat protectant for straighteners, curling irons, and blow dryers.
Do I need to use the full Long & Strong range?
While the leave-in works on its own, best results come from using it as part of the complete system including the shampoo, conditioner, and serum. Your stylist can recommend the right combination for your hair goals.
Is this suitable for colour-treated hair?
Yes, it's safe for colour-treated, chemically treated, and heat-styled hair. The antioxidant ingredients help protect against damage and keep hair healthy between salon visits.
Does it contain any allergens or fragrance?
Yes, the treatment contains fragrance (Keune's Soleil scent) and includes potential allergens like limonene and linalool. If you're sensitive to botanical extracts or fragrances, do a patch test before first use.
What size is the bottle and how long does it last?
The bottle contains 100ml (3.4oz). How long it lasts depends on your hair length and thickness, but most clients find it lasts several weeks with regular use.
Can I apply this to dry hair between washes?
The treatment is designed for application to clean, towel-dried hair for optimal absorption. For best results, apply after washing and conditioning as part of your styling routine.
Will this help with hair growth?
The Biomimetic Peptides help extend the hair growth cycle and the formula energises the scalp to create healthier conditions for growth. It's designed to reduce breakage and improve density, helping you retain length and achieve fuller-looking hair over time.
