In 1986, Farouk Shami answered the hair care prayers of women everywhere when he created BioSilk. Inspired by the luxurious and highly coveted fabric, Shami sought to bring the strength, smoothness, and shine of silk to dry, dull, and damaged hair. To accomplish this, the Original BioSilk Silk Therapy line uses hydrolyzed silk proteins to gently nourish and moisturize while also strengthening hair and repairing split ends.

BioSilk - Frequently Asked Questions

What makes BioSilk products so effective?

BioSilk products are formulated using hydrolyzed silk proteins which include almost all of the amino acids that are naturally found in hair. By using key components that exist in healthy hair, the products help hair heal with essential ingredients for sustainably healthy hair treatment.

I'm new to BioSilk. Where should I start?

BioSilk Silk Therapy Shampoo 12 Oz and BioSilk Silk Therapy Conditioner 12 Oz are part of the original BioSilk line, which is the most popular set from the brand, especially for customers who are unfamiliar with the brand. This line is formulated to work for any hair type. For styling needs, BioSilk Silk Therapy Finishing Spray Firm Hold 10 Oz is another great choice that is formulated to work together with the rest of the Silk Therapy line to nourish and strengthen hair.

What are the best BioSilk products for dry hair?

While the original Silk Therapy line is good for dry hair, BioSilk has a Hydrating Therapy line that will be even better if dryness is a specific problem for you. BioSilk Hydrating Therapy Shampoo 12 Oz and BioSilk Hydrating Therapy Conditioner 12 Oz offer all of the benefits of the Silk Therapy shampoo and conditioner with the additional benefits of quinoa, which helps retain moisture, and maracuja oil for even more hydration.

Do BioSilk products work on color-treated hair?

Yes! All BioSilk formulas are safe to use on hair that has been bleached or dyed. However, BioSilk Color Therapy Shampoo 12 oz was developed with color-treated hair in mind. On top of the amazing silk qualities of the original formula, Color Therapy products include gooseberry and bamboo to strengthen and repair damaged hair, rooibos to protect hair from further damage, and the patented VibraRiche® ingredient blend for longer-lasting color and increased vibrancy.

What BioSilk products are good for curly hair?

BioSilk shampoos and conditioners are safe and beneficial for curly hair, which needs moisture and specific care more than straight hair. A big concern for many people with curly hair is finding products that will maximize curl hold for multiple days without washing. BioSilk Rock Hard Gelee 6 Oz is the perfect choice for this task with a very firm and long-lasting hold. If you prefer a looser hold, then BioSilk Mousse 12.7 Oz is a good option as well.

Why are BioSilk bottles smaller than so many other brands?

A lot of hair care brands significantly dilute their products with water, so it looks like you're getting a great deal. However, those extra-large bottles of shampoo and conditioner may not work as well as you think. BioSilk products are extremely concentrated compared to many other options. This means that every drop of product is more powerful and effective than an alternative. You also don't need to use very much of a BioSilk product to effectively clean or treat all of your hair. Although the bottles are smaller, concentrated products often last longer because you need so little for each complete use.
