We believe that the hair spray will last longer because it hardens quickly when applied and has a lighter texture therefore making it last longer on hair.hair spray uses a special chemical called Polyvinylpyrrolidone(pvp), (va)copolymer,Acrylates Copolymer. These help both hair gel and hair spray hold in places for longer but we believe this can help.

Hairspray — in other words — a temporary, invisible hair net made of plastic-like ingredients that coats your hair and holds it in place. We understand that hairspray is a wet mist texture and is a light coating on the hair. Hair spray is made of long chain-like molecules called polymers, a liquid solvent(usually alcohol or water), and sometimes a propellant which pushes the mist out of the can. Hair gel is similar to hair spray; it is a hydrogel, meaning it is mostly water with long chains of polymers. Hair gel is a product you put on your hair to help it stay in place. It is thick and sticky, so it can hold hair in styles like spikes, curls, or smooth looks. Hair gel works because it coats each hair strand and forms a strong layer that keeps hair from moving. The main ingredient, called polymers, makes the gel sticky and strong. A polymer is a substance or material that has very large molecules or macromolecules made from many small repeating units called monomers that attach like beads to form a long chain, creating materials like plastics, DNA, proteins, and rubber. Hair gel does not cause a real chemical reaction when used. Instead, the water in the gel evaporates, and the polymers are left behind on the hair. These polymers form a coating that holds the hair in place. This process is a physical change, not a chemical reaction, because no new substance is created. Hairspray also does not cause a chemical reaction. When hairspray is sprayed, the liquid and gas evaporate quickly. The polymers remain on the hair as a thin film that helps hold the style. This is a physical change, not a chemical reaction, since the hair itself is not chemically changed.

Independent Variable: The amount of time we leave the hair gel and the hair spray in our hair. Controlled Variable: Amount of hairspray and hair gel, brand of hair gel or hairspray, hairstyle of the test subject. Dependent Variable: Which product lasted longer than the other

One of us applies hair gel to our hair, and the other uses hairspray. We get someone to hold the stop watches. We get two stepwatches because we want to see which product lasts longer than the other. There will be three trials, for more reliable results. We will do this procedure twice for reliability. Also because  Klarybel and I have different hair types, so my sister will assistant with the experiment since she has the same hairstyle as me. We spray the hair the same amount of gel onto the research participant for the first attempt –four hair sprays is equivalent to a pea-sized hair gel. On the second attempt, we will try the whole school day with my sister because her and I have the same hairstyle.

trial 1: The hairspray hardened immediately after appliance after applying it to Stephanie (assisstant).In the before picture you can see how Sophia’s(the one in the blue hoodie) hair is more straighter after applying the hair gel. But in the after photo, her hair is more wavy. The hairspray still held the hair together.  Trial 2: Sophia tries the hair spray, and it hardens. But in the middle of lunch, it starts softening, but still a little hard. The hair gel was softening in Stephanie’s observation. Hairpspray lasted longer.  Trial 3: The hair lifted up a little from Stephanie a little while after she applied it. Only a few strands are lifting up from Sophia’s hair. Hair spray lasted longer.  Trial 4: Since the hairstyle is supposed to be the sides smoothed back, the sides of Stephanie’s hair loosened and hung over her face. In Sophia’s hair, it's still hard. Hair spray lasted longer.  Trial 5: The hair spray hardened while the hair gel softened, so the hair was loose. Hairspray lasted longer. 

The hairspray lasted longer because the hair spray stayed consistent in hardening, while hair gel was in between softening and hardening. 

Hair gel does not last very long because it is designed for light-to-medium hold, and it has less polymers than hair spray.

As the liquid dries up in hairspray the polymers starts to create a dry stiff coating on the head often making it dry,flaky scalp and hairsprays typically  have more polymers than a hair gel.

The experiment seemed to have hairspray as the winner that may have been due to its polymers locking and holding the hair in place for longer. Throughout the experiment we noticed that no matter the hair of the person it seemed to stay in place. Their might’ve been more effective ways to do trials but we have done this to the best of our ability.

This experiment is important because it is meant for those who have fierce battles with their hair each morning and struggle to keep it neat by the afternoon.

Unequal measurements of hairspray and hair gel. 

No record of attempted first trial so it was not a part of the actual experiment.

Unspecified observations and it was not scientifically organized

Klarybel and I got our information from AI(Artificial Intelligence sources like ChatGPT), and Google. We also got the information about polymer off wikipedia, which is the free encyclopedia. We get the hair gel chemical reactions off https://chemistryislife.com/, and hair spray off How Everything Works. Hair gel sales graphs are off Market Data Forecast, and the hairspray sales graph off archivemarketresearch.com. 

we thanks the participant that let us test on their hair during this experiment stephanie capulong and Sophia capulong. We also thank our teacher Mrs. peper ,Aool,and CYSF for giving us this opperunity for this to happen.We thank the reasearch websites we used that were listed in the citions .
