   Pros:

   • Hair is smoother & softer for days after use
   • Leaves hair squeaky clean with no residue
   • Easy to use, spread & rinse

   Cons:

   • May not suit very fine hair
   • Conditioner is meant for towel-dried hair
   • Nice scent but doesn't last long

   Kerastase’s sulfate-free Discipline Bain Fluidealiste and Fondant Fluidealiste is a hydrating, cleansing, frizz-fighting, hair straightening shampoo and conditioning duo designed to create smoother, sleeker, softer, lighter, and more radiant tresses in fine or normal hair. It does this by sealing the hair fiber in its creamy, thick formula.

   If you’ve got curly, wavy, or just unruly, stubborn hair, this is for you. Softening agents and surface protectors help to make hair easier and more manageable to work with and leave you with softer, smoother, silkier strands. What’s also nice is how easily the shampoo lathers into thick, creamy suds, while the conditioner controls frizz and leaves hair looking sleek and lovely.

2. 2. Tec Italy Metamorfosi Temporary Hair Straightening Shampoo and Conditioner

   

   Price: $39.78

   Amazon Customer Reviews

   Shop at Amazon
   Pros:

   • Gives natural, healthy, strong shine
   • Works well to help straighten hair
   • Won't weigh hair down

   Cons:

   • Some had better results with others

   • Some found it pricey

   Metamorfosi Shampoo and Conditioner is a unique combination of Italian, American, and mesoamerican technology rolled into one. The temporary relaxing shampoo is perfect if you’ve got lots of curls and need more control over them or that annoying frizz, or if you’d simply love a break, with simple, straight locks instead. It also works to pre-treat less curly hair before being straightened, as the formula is meant to work well with flat irons or other heated styling tools to safely and effectively straighten hair, and it provides both resistance to moisture and thermal protection.

   Sunscreen-enriched with botanical proteins and silicones, the formula uses cystine complex W-S to clean, protect, strengthen, and fortify hair. The essential oil and mineral combination of tricone tricoerba, tricel-R, and tricosil protects the hair against heat, offering beautiful softness, texture, and shine.

   To use, wash hair with shampoo to start the relaxing process by massaging small amounts in evenly for 2-3 minutes and rinsing out. Follow with conditioner.

Can Shampoo Straighten Hair?

Hair straightening shampoos help to prep your hair for straight styling. If you have coarse, frizzy hair, this is an important step to make things easier before reaching for your flat iron or other styling tools.

There are several things you can do to get straighter hair without the drying, damaging effects of blow dryers or heated styling tools:

1. Blow dry with cold air
2. Sleep with wet hair
3. Use hair straightening shampoo and other straightening products
4. Apply a hair mask
5. Use plastic or velcro rollers
6. Wrap your hair with roller pins and a scarf
