The three factors determined by the pre-perm analysis in hair are hair porosity, elasticity, and overall hair health. Hair porosity helps determine how well the hair can absorb and retain moisture and chemicals. Elasticity indicates how well the hair can stretch without breaking. Overall hair health assesses the condition of the hair before applying any chemical treatment.

What determines the texture of hair?
Hair texture is largely determined by genetics. Factors such as the shape of the hair follicle, the diameter of the hair strand, and the level of moisture in the hair all contribute to whether hair is straight, wavy, curly, or kinky. Hair texture can also be influenced by environmental factors and hair care practices.
What is the meaning of microscopic hair analysis?
Microscopic hair analysis is the examination of hair samples under a microscope to determine characteristics such as color, shape, thickness, and abnormalities. This analysis can be used in forensic investigations to link individuals to a crime scene or to identify potential suspects. However, it is important to note that hair analysis has limitations and should be used in conjunction with other forms of evidence.
Why does jeramey have curly hair?
Jeramey likely has curly hair due to genetics. Hair texture is determined by the shape of the hair follicle, which is inherited from parents. curly hair results from follicles that are oval or asymmetrical in shape.
Does the color of your hair depend on how much heat it absorbs?

What types of clues can be obtained through hair analysis?
Hair analysis can provide clues about an individual's drug use history, exposure to toxins or heavy metals, nutritional deficiencies, and certain health conditions. It can also reveal information about the individual's lifestyle habits, such as diet and hair care products used.
Why is hair analysis considered unreliable as a method of testing for substances or toxins in the body?
Hair analysis is considered unreliable for testing substances or toxins in the body because external factors such as hair products, environmental exposure, and hair color can affect the results. Additionally, there is no standardized method for hair analysis, leading to inconsistencies in interpretation and accuracy.
What causes hair to change color?
Hair color is determined by the amount and type of melanin, a pigment, in the hair follicles. As people age, the production of melanin decreases, leading to gray or white hair. Other factors like genetics, stress, and environmental factors can also influence hair color changes.

Hair texture can also be influenced by environmental factors and hair care practices.
What are 5 things that can be determined by a single hair?
DNA profile - Hair can provide a source of DNA for identification purposes. Drug or toxin exposure - Hair analysis can reveal traces of drugs or toxins present in the body. Health information - Certain health conditions or deficiencies can be detected through analysis of hair composition. Environmental exposure - Hair can retain information about exposure to pollutants or chemicals in the environment. Nutritional status - Hair analysis can provide insight into an individual's nutritional intake and deficiencies.
What factors determine the variation in human hair color?
The variation in human hair color is determined by genetics, specifically the combination of different genes that control the production of melanin, the pigment that gives hair its color. Other factors such as age, hormones, and environmental influences can also play a role in hair color variation.
Is wavy hair genetic?
Yes, wavy hair is predominantly genetic. The texture and curl pattern of hair are determined by the shape of the hair follicle, which is inherited from parents. Other factors like hair care practices and products can also influence the appearance of wavy hair.
