Questions people ask about treatments and smoothing
Something else on your mind? Send a note from the contact page or ask at your consultation.
How long does a keratin smoothing treatment last?
Up to 3 months at Jenna Ellen Hair, washing out gradually with no line. Sulphate-free shampoo and less heat stretch it towards the full 3 months.
Does smoothing straighten my hair?
Cezanne and SmoothFiller soften wave and take out frizz rather than flattening the hair, so it still moves and can still be curled. For a properly straight finish, nanoplasty is the treatment: straighter, longer-lasting, and still formaldehyde-free.
What's the difference between keratin smoothing and nanoplasty?
Keratin smoothing (Cezanne, SmoothFiller) coats and seals the hair for a smoother, less frizzy version of your own texture, for up to 3 months. Nanoplasty works deeper to straighten the hair and holds for longer. Both are formaldehyde-free, both wash out gradually with no line, and the consultation decides which suits your hair and the finish you want.
Are keratin treatments good for hair?
Cezanne is formaldehyde-free and conditions the hair while it smooths, so it's suitable for coloured and lightened hair. The consultation confirms it's right for your hair before it's booked.
Can I colour and smooth on the same day?
Usually yes: colour first, then the smoothing treatment. Your stylist plans the order at consultation so both results hold.
How much does a keratin treatment cost in NZ?
Salon smoothing in Auckland is priced by length and density, and at Jenna Ellen Hair it's quoted at a free consultation so the number is exact for your hair rather than an estimate.
