HAIR PROTEIN SENSITIVITY CHART
Stretch Test
How to Complete test
Gently stretch a single strand of clean, damp hair between your fingers and observe how it behaves when you let go.
When to Perform and Purpose of Test
Before using protein-rich product to check natural elasticity, and after using protein-based product to see if stiffness increases.
Sign of Protein Overload
Hair snaps easily/quickly with little to no stretch. This is a sign that you may be experiencing / prone to protein overload.
If so, alternate protein-rich and moisture-rich products to maintain balance and use clarifying based product to remove protein build up if needed.
Signs Hair Needs Protein
Hair stretches too much before breaking, this is a sign that your hair is craving protein for structure.
Feel Test
How to Complete test
Run your fingers down a freshly washed, air-dried hair strand and pay attention to how it feels.
When to Perform and Purpose of Test
After using protein-rich product and moisture-rich product to compare how hair responds to each.
Sign of Protein Overload
Hair feels stiff, rough, or straw-like. this is a sign that you may be experiencing/ prone to protein overload. If so, alternate protein-rich and moisture-rich products to maintain balance and use clarifying based product to remove protein build up if needed.
Signs Hair Needs Protein
Hair feels overly soft, weak or limp, this is a sign that your hair is craving protein for
structure.
Sensitivity Test
How to Complete test
Apply a protein-rich product to one section of hair and a moisture-rich product to another section of hair.
Leave for about 15 minutes and rinse.
When to Perform and Purpose of Test
Before using protein-rich product to determine how hair absorbs protein-rich product and moisture-rich product.
Sign of Protein Overload
Hair becomes stiff and dry with protein-rich product, but feels better with moisture-rich product. This is a sign that you may be experiencing/ prone to protein overload. If so, alternate protein-rich and moisture-rich products to maintain balance and use clarifying based product to remove protein build up if needed.
Signs Hair Needs Protein
Hair feels stronger and bouncier with protein-rich product. This is a sign that your hair benefits from protein.
Water Test
How to Complete test
Place a single strand of clean hair into a glass of water, and observe for 5 minutes.
When to Perform and Purpose of Test
Place a single strand of clean hair into a glass of water, and observe for 5 minutes.
Sign of Protein Overload
Hair floats on top of the water, indicating resistance to absorbing protein or moisture. This is a sign that hair is low porosity and struggles to absorb moisture or protein. With low porosity hair, you may be prone to overload. If so, alternate protein-rich and moisture-rich products o maintain balance and use clarifying based product to remove protein build up if needed.
Signs Hair Needs Protein
Hair sinks quickly, meaning it absorbs protein and moisture easily. Thisis a sign that hair is high porosity and absorbs moisture or protein easily. With high porosity hair, your hair is craving protein for structure.
