Professional Stylist Experiences
Elena Rodriguez I have been using ISO Option 1 in my salon for over five years, and it is the only perming system I trust for my clients with fine hair. The thio-free formula is a game-changer because I never have to worry about that aggressive chemical smell or the “crunchy” over-processed feel that traditional perms leave behind. Just last week, I used it on a client who wanted a soft beach wave, and the built-in stop action timing ensured her hair stayed silky and shiny while holding a perfect, bouncy wave.
Marcus Sterling Finding a product that can actually penetrate thick, gray hair without frying the cuticle used to be a challenge until I started stocking ISO Option 3. I recently performed a service on a client with very resistant, coarse hair who had given up on perms, and the results were stunningly crisp and firm. The Isoamine technology really does make a difference in how evenly the lotion penetrates, giving me a consistent curl pattern from the roots all the way to the ends every single time.
Sarah Jenkins The ISO Option EXO is my absolute go-to for my long-haired clients who want that extra “oomph” and definition that stays energized for weeks. I love the exothermic application process because it feels like a premium, high-tech service for the client, and the thermal activation ensures even the heaviest hair doesn’t fall flat. The definition I get on long, resistant strands is unparalleled, and the fact that it protects the hair’s integrity while delivering such a strong curl is why I won’t use anything else.
ISO Perms FAQ
What makes ISO Perms different from traditional perming lotions?
ISO Perms utilize a patented thio-free formula containing Isoamine or Isohaline, which allows for deeper and more even penetration into the hair shaft without aggressively opening the cuticle. This technology ensures that the hair remains healthy and shiny while achieving a more resilient and natural-looking curl compared to traditional alkaline perms.
Can I use ISO Perms on hair that has been color-treated?
Yes, specifically ISO Option 2 is designed for all color-treated hair, while other options are compatible with tinted hair up to 20 volume. The gentle formula helps maintain color integrity and prevents the “frizzy” look often associated with chemically treating colored hair.
How long does the processing time usually take?
Most ISO Perm options feature a built-in stop-action timing system that typically processes in approximately 20 minutes. However, it is always recommended to perform test curls during the service, especially for porous or highly resistant hair types, to ensure the desired wave pattern is achieved.
Is the ISO Option Exo better for long hair?
The Option Exo is an exothermic (self-heating) formula, making it the ideal choice for long, resistant hair. The thermal activation provides the additional energy needed to ensure the curl is defined and lasting from the roots to the heavy ends of longer hair strands.
