The primary function of a conditioner is to moisturize and detangle hair after shampooing. This strengthens the hair and reduces breakage.
Keratin is a protein that provides strength and structure to hair. It's essential for maintaining hair's integrity and resilience.
Biotin, also known as Vitamin B7, is widely recognized for promoting hair growth and improving hair health by strengthening hair follicles.
'SLS' stands for Sodium Lauryl Sulfate, a common ingredient in cleaning products that helps produce foam and remove dirt and oil from hair.
Argan Oil, derived from the kernels of the argan tree, is rich in essential fatty acids and Vitamin E. It is known for its nourishing and moisturizing properties.
Sulfate-free shampoos are known for reducing scalp irritation and dryness because they are less harsh and do not strip the natural oils from the hair and scalp.
pH balance in hair care is crucial for maintaining the moisture and strength of hair. A balanced pH helps the cuticle to stay sealed, locking in moisture and nutrients.
Vitamin A is essential for the production of sebum, which helps moisturize the scalp and keeps hair healthy by providing vital nutrients and moisturization.
A heat protectant spray forms a barrier on the hair shaft, thus protecting it from the damaging effects of heat styling tools like flat irons and blow dryers by preventing moisture loss.
Leave-in conditioner provides ongoing moisture and protection throughout the day, helping to detangle while keeping hair soft and manageable without needing to rinse off.
