I apologize for bump this old thread, but I would like to share my experience in this matter, since when I was looking for good advice on this topic for myself
I had vibrant red hair for over two years and honestly tried every product under the sun! Red hair is high maintenance but looks amazing so it's worth it.
This is what I used to use:
- PPS Violet Redzz Shampoo (every day shampoo) This was my favourite shampoo, it's a really vibrant, bright red & deposits colour really well without weighing the hair down like other colour depositing products. The range also has another colour 'Copper Redz'.
- Redken Colour Extend (moisturizer)
Best Hair Moisturizer of 2018 - Buyer’s Guide and Review I searched high and low for a good colour deposit conditioner, but there were none I really liked as much as the Redken range so in the end I used this conditioner & added a bit of Fudge Cherry Bomb.
- Vitality Espresso Red Colour (treatment) I LOVE this treatment, it adds so much colour and shine to your hair. The only downfall is it smells quite bad and is also very strong so stains your hands/nails so best to wear gloves (at least you know it works hehe)
