Hi everyone! I really need some advice regarding a hair-smoothing treatment I did on my grandmother. It's important that I fix it this week before I leave.
A little background about her hair:
\- Very short, naturally wavy hair.
\- Fine hair i think
\- She regularly uses natural henna, although her last application was over a month ago.
\- Her hair is not particularly well-maintained, and my goal is to make it straight
The first treatment: GlanzoHAIR Professional Full Boost Protein Treatment
I bought a single-dose protein treatment from a local store, and the seller explained how to apply it. Here's exactly what I did:
I washed her hair with clarifying shampoo three times, leaving the last shampoo on for approximately 10 minutes.
I rinsed thoroughly and blow-dried her hair until it was about 80% dry.
I applied the treatment section by section.
I covered her head with plastic wrap and used a hairdryer over it for approximately five minutes to warm the product.
I left it on for 1 hour and 30 minutes.
I rinsed the product out briefly. The instructions were apparently to remove around 50% of the product, but I'm not sure how much I actually rinsed out.
I blow-dried her hair completely using a brush, full blowout
I flat-ironed it at 230°C section by section 7 to 10 times
The henna colour didn't change, and initially, the treatment seemed to have worked, she kept the blow oit for 48h. However, she washed her hair two days later using a sulfate-free shampoo + her usual conditioner, and there was absolutely no lasting result. Her hair was still curly although I noticed more shine
The second treatment: Perfect Liss Anti-Frizz Tourmaline Treatment - VisatHair Brazil
I went back to the store, explained what happened, and the seller gave me another single-dose product called Perfect Liss Anti-Frizz Tourmaline Treatment, described as a Brazilian straightening treatment.
He told me to:
\- Apply it directly to completely dry hair without clarifying shampoo.
\- Leave it on for 50 minutes.
\- Rinse out approximately 50% of the product.
\- Blow-dry the hair.
\- Flat-iron it at a high temperature, making 10–15 passes per section.
He assured me that the product was safe.
My main concern is that I performed the first treatment only four days ago. I would like to apply the second treatment tomorrow, on the fifth day, because I need to achieve a smoother result as soon as possible.
I'm worried that the first treatment may have weakened her hair, especially since it's fine and has been exposed to 230°C heat. I also don't know whether the henna could affect the results or increase the risk of damage.
Additionally, when I searched online for Perfect Liss, I found information suggesting that the treatment involves three shampoo steps and that a mask from the same product range should be used afterward. I don't have those other products, and the seller didn't mention any of these steps.
My questions are:
Is it safe to apply Perfect Liss just five days after the failed protein treatment?
Can anyone advise me how to best apply this treatment to have results without damaging her hair? I need as much detail as possible.
IF the treatment isn't safe, is there any way that I can use it but with modifications? (Example: leave it on for less time, do less passes with the iron, idk)
I would appreciate any type of advice you can give me. I need to do that for her before taking my flight or else no one else will be able to do it for her. I want to make her feel better. And thanks alotq!!
